Speaker 1: All right, time to dive in. Today. We're going to
Speaker 1: be looking at rust specifically how it's used in web development.
Speaker 1: And you know what, you've given us a really interesting
Speaker 1: mix of stuff to go through. Oh yeah, yeah, we've
Speaker 1: got excerpts from this book practical Rust Web projects, and
Speaker 1: then some of the official documentation for Rust itself. So yeah,
Speaker 1: it should be fun to dig into.
Speaker 2: Yeah, that's a great combo. There's like we can get
Speaker 2: the practical side and then dive into like all the
Speaker 2: nitty gritty technical stuff that you know makes it.
Speaker 1: Tick totally, and right off the bat, the book highlights
Speaker 1: these three big strength of Rust, right, security, concurrency, and
Speaker 1: then low level control. And for someone building like a website,
Speaker 1: especially one that you know, handles sensitive stuff or needs
Speaker 1: to be super responsive. I mean, these features sound almost
Speaker 1: too good to be true.
Speaker 2: Well let's break them down. First off, security, I mean,
Speaker 2: when it comes to the web, right, the stakes are high,
Speaker 2: like really high. One little vulnerability and oh boy, things
Speaker 2: can go south fast.
Speaker 1: Right.
Speaker 2: What's wild about Rust is that it can actually like
Speaker 2: stop a lot of common security problems right at compile time.
Speaker 1: Wait, so you mean before the code even runs exactly.
Speaker 2: It's like the compiler is this super thorough code inspector.
Speaker 2: You know, it's checking for like memory errors, data rases,
Speaker 2: and all these other sneaky things that could like create
Speaker 2: security holes. Having that kind of scrutiny at the compilation stage,
Speaker 2: m hm, it gives developers a huge advantage, a level
Speaker 2: of like confidence that's really hard to get with other languages.
Speaker 1: That's a powerful advantage for sure, especially like you said,
Speaker 1: these days where everyone's so concerned about security. Right, But okay,
Speaker 1: what about concurrency? I mean, websites these days, they have
Speaker 1: to handle so much at once, right, like user interactions,
Speaker 1: database queries, all these background processes. Just seems like a
Speaker 1: nightmare to manage all that efficiently and you know safely.
Speaker 2: You're right. Concurrency is a major challenge in web development.
Speaker 2: Like the old ways of doing things, they often lead
Speaker 2: to code that's like super complex and easy to mess up.
Speaker 2: I mean, but rust it tackles this head on with
Speaker 2: its ownership and borrowing system. This ensures that your code
Speaker 2: is thread safe, but without like sacrificing performance. Honestly, it's
Speaker 2: a game changer for building like high performance web apps
Speaker 2: that you can actually rely on.
Speaker 1: Okay, I'm starting to see why people are so excited
Speaker 1: about Rust. Now, the book also mentions low level control
Speaker 1: as a strength. But is that something that you know,
Speaker 1: a typical web developer really needs to worry about. It
Speaker 1: sounds kind of intimidating, to be honest.
Speaker 2: You don't have to be like a hardware guru or anything,
Speaker 2: but having that low level control can be a real asset,
Speaker 2: especially when you're like trying to squeeze out every bit
Speaker 2: of performance.
Speaker 1: Okay.
Speaker 2: It basically lets you fine tune how your code talks
Speaker 2: to the underlying system, you know, so you can really
Speaker 2: get things humming.
Speaker 1: So for tasks that are like really resource intensive, Rust
Speaker 1: can give you that extra edge. Exactly interesting, And speaking
Speaker 1: of putting all this into practice, the book walks through
Speaker 1: this project called cat decks. Yeah, it's this Pokemon inspired
Speaker 1: index of like cat breeds.
Speaker 2: I love it, Yeah, CatEx. Yeah, it's a super fun
Speaker 2: way to show how you can use Rust to build
Speaker 2: actual web applications.
Speaker 1: Totally, And the book explains how cat x uses server
Speaker 1: side rendering with Rust. Now, I'm more familiar with those
Speaker 1: like drag and drop website builders, So can you maybe
Speaker 1: break down what server side rendering actually is and why
Speaker 1: it matters here.
Speaker 2: Sure. So in a service side rendered website, basically the
Speaker 2: server is dynamically building those HTML pages for each request, right,
Speaker 2: so instead of sending like a static file, it's assembling
Speaker 2: the page on the fly, pulling in data from like databases,
Speaker 2: any user input, and all those other kind of moving parts.
Speaker 2: This approach has some real advantages, especially for sites with
Speaker 2: a lot of content or complex interactions.
Speaker 1: So the server is doing more work upfront, but then
Speaker 1: it delivers a fully formed page to the user's browser.
Speaker 2: Right exactly. And in the case of cats, imagine the
Speaker 2: server grab an info about each cat breed from a database,
Speaker 2: plugging that into a predesign htmail template, and then boom,
Speaker 2: sending that complete page to the user.
Speaker 1: That makes sense, But the book also brings up this
Speaker 1: potential issue, right, what happens when that cadex database gets huge,
Speaker 1: constantly generating those pages from scratch. It seems like that
Speaker 1: could slow things down.
Speaker 2: Right, Yeah, you've hit on a key point. If you've
Speaker 2: got tons of data and it's changing all the time,
Speaker 2: that pure server side rendering approach, it can become a bottleneck.
Speaker 2: And that's where the book's discussion of rest APIs with
Speaker 2: rust comes in.
Speaker 1: Rest APIs Okay, I've heard that term, but I'm still
Speaker 1: a little fuzzy on what it actually means. Can you
Speaker 1: break that down for us?
Speaker 2: For sure? Think of a rest API as this specialized
Speaker 2: way for the server and the client, which would be
Speaker 2: like the user's web browser to talk to each other.
Speaker 2: Instead of sending full blown web pages, the API sends
Speaker 2: data like in a structured format. It could be Jason
Speaker 2: or xmount, things like that, and then that data can
Speaker 2: be used by the client side code, which is usually
Speaker 2: the JavaScript, to dynamically build the page right there in
Speaker 2: the user's browser.
Speaker 1: So it's more like a team effort, right, instead of
Speaker 1: this server doing all the work, it's kind of sharing.
Speaker 2: The load exactly. The server's like here's the raw data,
Speaker 2: and the client side code is like, all right, I'll
Speaker 2: assemble and present this. And that can seriously boost performance,
Speaker 2: especially for data heavy websites like we were talking about
Speaker 2: with cadecs.
Speaker 1: That's really clever, but it also seems like you need
Speaker 1: to understand like both the server side stuff and the
Speaker 1: client side stuff, right, you do.
Speaker 2: But the cool thing is that Rust plays really well
Speaker 2: with front end technologies like JavaScript. You can build that
Speaker 2: API with Rust, serving up data nice and efficiently and
Speaker 2: then use whatever JavaScript framework you like to handle all
Speaker 2: the client side logic. And like how it looks okay?
Speaker 1: So Rust is like the powerful engine on the back
Speaker 1: end feeding the data to the front end, where JavaScript
Speaker 1: takes over to create the user interface.
Speaker 2: Yep, that's a good way to put it now.
Speaker 1: The book also mentions using web sockets for real time
Speaker 1: two way communication.
Speaker 2: Ah, I can see.
Speaker 1: That'd be useful for like a live chat feature on
Speaker 1: the Cattex site. Right.
Speaker 2: Absolutely. Web sockets create this persistent connection between the server
Speaker 2: and the client, so you can have that constant back
Speaker 2: and forth flow of data. What was up? A ton
Speaker 2: of possibilities live chat, you got it, real time notifications,
Speaker 2: collaborative editing, all sorts of cool stuff.
Speaker 1: Wow, RUSS seems to have like all the bases covered.
Speaker 1: But let's be real, managing all these different pieces the server,
Speaker 1: the database, the web sockets, it sounds pretty complex. I'm
Speaker 1: already getting server management anxiety just thinking about it.
Speaker 2: I hear you. It can seem daunting, but that's where
Speaker 2: the idea of serverless computing comes in. And hey, guess what.
Speaker 2: The Practical Rust Web Projects book actually dives into that too.
Speaker 1: Serverless. Wait, you mean I could potentially build this whole
Speaker 1: Catdex website without actually managing any servers myself.
Speaker 2: You got it.
Speaker 1: That sounds amazing, But how does that even work in practice?
Speaker 2: In a serverless environment? You focus on writing your apps
Speaker 2: logic as functions, and then a cloud provide like AWS.
Speaker 2: They handle all the underlying stuff, the servers, the scaling,
Speaker 2: load balancing, all that. You basically just deploy your code
Speaker 2: and cloud takes care of the rest.
Speaker 1: So I can just focus on the code and let
Speaker 1: the cloud handle all those infrastructure headache exactly. That's a
Speaker 1: game changer. Now, the book mentions using AWS lambda specifically
Speaker 1: for serverless rust, is that like a viable approach.
Speaker 2: It's not just viable, it's a powerful combo. Awslambda lets
Speaker 2: you upload your rust functions and then it automatically runs
Speaker 2: them on demand. It scales them up or down based
Speaker 2: on traffic, so you don't have to worry about it. Yeah,
Speaker 2: and get this. The book even talks about using this
Speaker 2: thing called the serverless framework. Okay, it lets you define
Speaker 2: your entire infrastructure as code.
Speaker 1: Wait, so I could like write code to define my servers,
Speaker 1: my database, my whole setup. That's incredible, right.
Speaker 2: This approach brings a whole new level of like flexibility
Speaker 2: and automation to web development. You can version control your infrastructure,
Speaker 2: easily deploy changes, and just like focus on building great
Speaker 2: apps without getting bogged down and all that server stuff.
Speaker 1: All right, this is officially mind blowing. And to top
Speaker 1: it all off, the Rust documentation you sent me talks
Speaker 1: about compiling to this thing called web assembly. Apparently it
Speaker 1: lets Rust run like right in the browser. Is this
Speaker 1: for real?
Speaker 2: Oh yeah, web assembly is a real game changer. It
Speaker 2: lets languages like Rust run at near native speeds within
Speaker 2: web pages. It's opening up possibilities that we just couldn't
Speaker 2: do with JavaScript alan before.
Speaker 1: So instead of relying solely on JavaScript, we could use
Speaker 1: Rust to build these like super high performance parts of
Speaker 1: a website that run directly in the browser exactly.
Speaker 2: And this is especially exciting for things that need like
Speaker 2: crazy performance, think complex calculations, data visualizations, maybe even game development.
Speaker 2: The documentation even highlights this Rust powered image recizer that
Speaker 2: runs entirely in the browser.
Speaker 1: So instead of uploading a huge image and then resizing
Speaker 1: it on the server, we could offload that processing to
Speaker 1: the user's browser with web assembly.
Speaker 2: Exactly, and imagine the possibilities if we combined this with cattex.
Speaker 2: Oh yeah, you could resize images on the client side
Speaker 2: before they're even uploaded. That would save bandwidth and reduce
Speaker 2: the load on the server. Pretty amazing stuff.
Speaker 1: This is truly remarkable. I feel like we've only just
Speaker 1: scratched the surface of what Rust can do in the
Speaker 1: web development world. I'm definitely eager to explore this further.
Speaker 2: Yeah, there's a lot to uncover. It seems we've got
Speaker 2: you hook on the potential of Rust for web development.
Speaker 1: Hooks doesn't even begin to cover it. You mentioned this
Speaker 1: web assembly image recizer and the documentation says it can
Speaker 1: reach near native speeds. Is that level of performance really
Speaker 1: possible inside a web browser?
Speaker 2: Oh, it's not just hype. Web assembly really is a
Speaker 2: game changer when it comes to web performance. By compiling
Speaker 2: languages like Rust to this like low level bycode, we
Speaker 2: can really tap into the power of the user's hardware.
Speaker 1: So we're basically like bypassing some of those limitations of
Speaker 1: JavaScript and getting a more direct line to the browser's capabilities.
Speaker 2: That's a great way to put it. Web assembly lets
Speaker 2: us build web apps with performance that used to only
Speaker 2: be possible with like native desktop applications, and that has
Speaker 2: huge implications for well pretty much everything, complex visualizations, immersive games,
Speaker 2: you name it.
Speaker 1: This opens up a whole new world. But is web
Speaker 1: assembly limited to just those smaller kind of self contained
Speaker 1: modules like the image recizer example. Could we build entire
Speaker 1: web applications using Rust and web assembly.
Speaker 2: Now that's where things get really exciting. We're already seeing
Speaker 2: frameworks like You pop up and they let developers build
Speaker 2: entire front end applications with Rust and web assembly. Really yeah,
Speaker 2: You is heavily inspired by those popular JavaScript frameworks like React,
Speaker 2: but it brings all those Rust benefits, the safety, the performance,
Speaker 2: the reliability right to the front end.
Speaker 1: So instead of JavaScript handling the user interface, we could
Speaker 1: have Rust powering both the service side logic and the
Speaker 1: client side interaction exactly.
Speaker 2: And with Rust's focus on memory safety and predictable behavior,
Speaker 2: we can create web applications that are not only super fast,
Speaker 2: but also really stable and much less likely to crash.
Speaker 1: This is like changing the whole game. It really flips
Speaker 1: the traditional way we think about web development on its head.
Speaker 1: Now I want to circle back to that Practical Rust
Speaker 1: Web Projects book and the catdex example for a minute,
Speaker 1: the book explains how to build a server side rendered website.
Speaker 1: What are some of the key steps in setting up
Speaker 1: a site like that with rust?
Speaker 2: Well, the book used this framework called actis Web, which
Speaker 2: is known for being like really fast and flexible. So
Speaker 2: the first thing is defining the structure of your application,
Speaker 2: like creating the blueprints. You know, you set up roots
Speaker 2: to handle incoming requests. You define handlers which contain the
Speaker 2: logic to process those requests and send back responses that
Speaker 2: kind of thing.
Speaker 1: So it's like mapping out all the different parts of
Speaker 1: your website and defining how each section will respond to
Speaker 1: what the user does exactly.
Speaker 2: You're basically creating a roadmap for how your web application
Speaker 2: will function. Then the book gets into using handlebars, which
Speaker 2: is a templting engine. It lets you embed dynamic content
Speaker 2: within your HTML files. This is where you start pulling
Speaker 2: in data from databases and other sources to make those
Speaker 2: pages dynamic.
Speaker 1: So instead of having static HTML files, we're using these
Speaker 1: templates that can be filled in with real time data,
Speaker 1: making the website more interactive and engaging.
Speaker 2: Exactly. Handlebars is a great way to separate the structure
Speaker 2: of your HTML from the dynamic content, which keeps your
Speaker 2: code cleaner and easier to maintain. Of course, you can't
Speaker 2: have a web application without a database. The Kadex project
Speaker 2: uses Diesel, which is a really robust ARM that stands
Speaker 2: or object relational mapper, and it basically makes it way
Speaker 2: easier to work with databases and Rust.
Speaker 1: Ah Diesel, I remember reading about that, but if I'm
Speaker 1: being honest, databases still kind of intimidate me. It feels
Speaker 1: like a whole other world to learn.
Speaker 2: I get it. Databases can be complex, but that's exactly
Speaker 2: why Diesel is so great. It lets you interact with
Speaker 2: your database using familiar Rust syntax. It handles a lot
Speaker 2: of the complexity of writing raw SQL queries for you.
Speaker 1: So what it's like having a translator that speaks both
Speaker 1: Rust and SQL, making it easier for my application to
Speaker 1: talk to the database.
Speaker 2: Perfect analogy. Diesel streamlines the whole process of working with
Speaker 2: databases in Rust, making it much more approachable even for
Speaker 2: developers who aren't database gurus.
Speaker 1: That's a relief. Now. The book mentions using Docker to
Speaker 1: set up a Postgres school database. I've heard of Docker,
Speaker 1: but can you give me like a quick explanation of
Speaker 1: what it is and why we need it here.
Speaker 2: Docker is awesome for creating containerized environments. Think of a
Speaker 2: container as like a lightweight, self contained package. It's got
Speaker 2: everything your application needs to run, the code, libraries, dependencies,
Speaker 2: even the operating system. Oh wow. In the cattext project,
Speaker 2: you use Docker to spin up a postgrescool database instance
Speaker 2: really quickly and easily. You don't have to go through
Speaker 2: all the hassle of installing and configuring it manually on
Speaker 2: your own system.
Speaker 1: So it's like having a pre built, portable environment that
Speaker 1: I can use to run my database exactly.
Speaker 2: Doctor makes setting up and managing the infrastructure for your
Speaker 2: web application a breeze.
Speaker 1: All right, back to Diesel. How does it actually handle
Speaker 1: the connection to the database. I imagine managing those connections
Speaker 1: efficiently is really important for performance.
Speaker 2: Right, You're right it is. Diesel uses something called a
Speaker 2: connection pool, which is basically a bunch of pre established
Speaker 2: connections to the database. So when your application needs to
Speaker 2: run a query, it borrows a connection from the pool,
Speaker 2: uses it, and then puts it back when it's done.
Speaker 1: Okay.
Speaker 2: This avoids the overhead of creating a brand new connection
Speaker 2: for each request, which can really bog things down.
Speaker 1: So it's like having a dedicated lane at a toll booth,
Speaker 1: so we don't have to wait in line every time
Speaker 1: we need to get to the database.
Speaker 2: Uh huh. I like that the connection pool keeps things
Speaker 2: flowing smoothly. Now, earlier we were talking about how concurrency
Speaker 2: is one of Russ's big strengths. Right, I'm curious how
Speaker 2: does Diesel handle concurrent database access? Wouldn't be a problem
Speaker 2: if multiple threads were all trying to use the database
Speaker 2: at the same time.
Speaker 1: Rate question, and it highlights a key thing about databases.
Speaker 1: By default, Diesel uses synchronous IO for database operations, so
Speaker 1: each database request will block the thread until it's finished. Now,
Speaker 1: that might seem like a limitation in a concurrent environment,
Speaker 1: but Rust provides a solution with this feature called web
Speaker 1: dot bloc weblock. What does that do?
Speaker 2: Webb block lets you move blocking operations like database queries
Speaker 2: off to a separate threadpool so they don't hold up
Speaker 2: the main thread, which needs to be free to handle
Speaker 2: incoming requests and keep your web application responsive.
Speaker 1: So it's like having a dedicated team of workers handling
Speaker 1: the database tasks while the main team focuses on serving
Speaker 1: those Web requests exactly.
Speaker 2: Web byblock helps you harness the power of concurrency without
Speaker 2: sacrificing the responsiveness of your app. It really shows how
Speaker 2: Rust lets developers write code that is both efficient and safe,
Speaker 2: even when dealing with tricky stuff like database interactions.
Speaker 1: This is all so fascinating. It's amazing to see how
Speaker 1: all these pieces fit together. The framework, the splitting engine,
Speaker 1: the arm, and Rust's concurrency features. They all come together
Speaker 1: to create this powerful and efficient web development ecosystem.
Speaker 2: It really is a testament to how thoughtfully Rust and
Speaker 2: its whole ecosystem have been designed.
Speaker 1: But let's be real, building a website isn't just about
Speaker 1: showing static content. We want users to actually interact with it,
Speaker 1: submit data, have those dynamic experiences. How does Rust handle
Speaker 1: things like forms and user input.
Speaker 2: Well, the cattex project actually demonstrates this. It builds a
Speaker 2: form for adding newcats to the database. It shows how
Speaker 2: to handle HTTP post requests, process the data from the form,
Speaker 2: and then interact with the database to store that new information.
Speaker 1: So it's like creating a conversation between the user and
Speaker 1: the application. The user provides input and then the application
Speaker 1: response by updating the database and maybe showing some feedback
Speaker 1: or updated content.
Speaker 2: You got it. Handling forms and user input is essential
Speaker 2: for web development, and Rust has all the tools and
Speaker 2: libraries you need to do it securely and efficiently. You
Speaker 2: can validate user input, sanitize data to prevent security problems,
Speaker 2: and provide clear error messages if things go wrong. It's
Speaker 2: all about making a smooth and reliable experience for the user.
Speaker 1: This is all starting to click for me. I'm actually
Speaker 1: feeling like I could build a website using Rust.
Speaker 2: I think you absolutely could, and remember that Practical Rust
Speaker 2: Web Projects book is there to guide you every step
Speaker 2: of the way. Right. The great thing about Rust is
Speaker 2: that its strong type system and the compiler are like
Speaker 2: your partners in crime. They'll catch errors early on and
Speaker 2: help you write really solid, dependable.
Speaker 1: Code that's encouraging to hear. Now, speaking of real world applications,
Speaker 1: let's talk about image uploads. I can't imagine cat des
Speaker 1: without a way to show off pictures of all these
Speaker 1: adorable cats. How does Rust handle file uploads?
Speaker 2: The cat dex project covers that too, yea. It shows
Speaker 2: how to handle file uploads using multipart form data, which
Speaker 2: is a standard way of sending files over the web.
Speaker 2: You can receive those cat picks from users, process them
Speaker 2: in your RUST code, and then store them either on
Speaker 2: the servers, file says, or a cloud storage service like
Speaker 2: AWSS three.
Speaker 1: So it's like adding a virtual photo album to the
Speaker 1: Catdex website where users can share their own cat photos Precisely.
Speaker 2: Handling file uploads opens up so many possibilities for building rich,
Speaker 2: interactive web applications, and because RUSS focuses on safety and
Speaker 2: error handling, you can be sure that the process is
Speaker 2: robust and secure, protecting your application from potential vulnerabilities.
Speaker 1: This is incredibly impressive. We've covered a lot, from the
Speaker 1: basics of server side rendering to the details of database interactions,
Speaker 1: form handling, and even file uploads. It's amazing to see
Speaker 1: how seamlessly Rust brings all these pieces together into a
Speaker 1: complete web development ecosystem.
Speaker 2: And we're not done yet. There's still so much to explore,
Speaker 2: like the ins and outs of deployment, how to handle
Speaker 2: errors effectively, and the overall impact Rust is having on
Speaker 2: the future of web development.
Speaker 1: I can't wait to dive deeper, but for now, I
Speaker 1: think we need a moment to let all this sink in.
Speaker 2: Yes, there's definitely a lot to process. We'll pick up
Speaker 2: our explorations soon.
Speaker 1: Okay, so I think I'm caught up. Last week left off,
Speaker 1: we were talking about image uploads for our Imaginary Catdex website,
Speaker 1: and the book mentions how important it is to handle
Speaker 1: those uploads, you know, securely. Makes sense, especially when you're
Speaker 1: dealing with stuff that users are sending in.
Speaker 2: Oh. Absolutely, security is like the top priority, especially with
Speaker 2: user generated content, right. You always have to be on
Speaker 2: lookout for those those sneaky uploads that could, you know,
Speaker 2: try to exploit weaknesses in your app or like mess
Speaker 2: with your server.
Speaker 1: Yeah, so it's not just about making sure those cat
Speaker 1: picks are cute. We also got to make sure they're
Speaker 1: not like hiding any digital viruses or something exactly.
Speaker 2: You got to be really careful about validating file types,
Speaker 2: sanitizing the input, and just generally protecting against potential attacks. Luckily,
Speaker 2: RUSS has a really strong set of tools and libraries
Speaker 2: that let you build those safeguards right into your application
Speaker 2: from the get go.
Speaker 1: That's good to hear. It sounds like Rust encourages developers
Speaker 1: to think about security from the very beginning, just like
Speaker 1: tack it on as an afterthought exactly.
Speaker 2: And that focus on security is a big reason why
Speaker 2: Rust is becoming so popular, especially in areas where reliability
Speaker 2: and safety are absolutely critical.
Speaker 1: Right, okay, so let's switch gears a bit and talk
Speaker 1: about the visual side of our CatEx site. We've covered
Speaker 1: the back end logic, the database stuff, the file uploads,
Speaker 1: but what about the front end, the part that users
Speaker 1: actually see and interact with. You know, technologies like CSS
Speaker 1: and JavaScript are essential for making a modern looking website.
Speaker 1: How does Rust work with those?
Speaker 2: That's a great question. So Rust itself is mainly focused
Speaker 2: on the back end logic, but it plays very nicely
Speaker 2: with front end technologies. You can still use your favorite
Speaker 2: CSS frameworks for styling, and of course JavaScript for all
Speaker 2: those interactive elements. And remember web assembly that we talked
Speaker 2: about earlier. That actually allows for even tighter integration, letting
Speaker 2: you run Rust code directly in the browder right alongside
Speaker 2: your JavaScript.
Speaker 1: So it's not like an either situation. We can use
Speaker 1: the best tools for each part of the application and
Speaker 1: have them all work together smoothly.
Speaker 2: Exactly. You can take advantage of the strengths of each
Speaker 2: technology to create a well rounded, high performing web application.
Speaker 2: For example, you could build the core logic and the
Speaker 2: API of your website using Rust, which gives you that
Speaker 2: robustness and efficiency on the back end, and then use
Speaker 2: a JavaScript framework like React or viewtas to create a
Speaker 2: dynamic and interactive user interface on the front end.
Speaker 1: Makes sense, Okay, Now, one thing that always kind of
Speaker 1: stresses me out is error handling. Oh yeah, websites can
Speaker 1: be pretty complex and things bound to go wrong sometimes right,
Speaker 1: network issues, database errors, unexpected user input, all that stuff.
Speaker 1: How does Rust approach error handling to make our applications
Speaker 1: more resilient.
Speaker 2: Rust has a very sophisticated error handling system that basically
Speaker 2: forces you to think about potential errors and handle them gracefully.
Speaker 2: Unlike some languages where errors are kind of ignored or
Speaker 2: handled with these generic exceptions, Rust makes you be very
Speaker 2: specific about the types of errors that might happen and
Speaker 2: how you want to deal with it.
Speaker 1: So instead of our catnecks website like completely crashing if
Speaker 1: something goes wrong, we can anticipate those issues and provide
Speaker 1: helpful air messages, maybe even suggest some alternative actions for
Speaker 1: the user.
Speaker 2: Right exactly, Well handled errors are crucial for a good
Speaker 2: user experience, and Rust gives you the tools and the
Speaker 2: structure to make that happen.
Speaker 1: That's awesome. Now, speaking of making things happen, let's talk
Speaker 1: about deployment. Getting a website from our development environment out
Speaker 1: into the real world where people can use it. That
Speaker 1: can be a pretty scary process. How does Rust help
Speaker 1: with that.
Speaker 2: One of the things that makes Rust so great for
Speaker 2: web development is that it can create these self contained,
Speaker 2: statically linked binaries. Okay, what that means is you can
Speaker 2: compile your Rust application into a single executable file that
Speaker 2: has everything it needs to run. It doesn't need external
Speaker 2: libraries or a complicated runtime environment.
Speaker 1: So it's like pack in a suitcase for a trip,
Speaker 1: but you've got everything you need right there. No need
Speaker 1: to worry about adapters or missin essentials.
Speaker 2: Huh exactly. That self contained nature makes deployment super simple.
Speaker 2: You can just copy that compile binary to your server
Speaker 2: and it should just work without any compatibility problems or
Speaker 2: complicated setupsteps.
Speaker 1: That sounds incredibly convenient. Okay, last question before we wrap
Speaker 1: up this amazing deep dive. The documentation mentions that Rust
Speaker 1: can be used not only for web development, but also
Speaker 1: for creating like command line tools. Could we use Rust
Speaker 1: for everything in our CADEX site, the front end, the
Speaker 1: back end, even some behind the scenes tasks.
Speaker 2: You've hit on one of the most exciting things about Rust.
Speaker 2: It's incredibly versatile. It's not just a web development language.
Speaker 2: You can use it for all sorts of things. You
Speaker 2: could write command line tools to automate tasks, build the
Speaker 2: server side logic for your web app, create those high
Speaker 2: performance web assembly modules for the browser, and even explore
Speaker 2: things like game development or embedded systems.
Speaker 1: So Rust is like a multi talented performer capable of
Speaker 1: handling a whole range of different tasks. Kind of like
Speaker 1: a Swiss army knife for software development.
Speaker 2: Huh huh. That's a perfect way to put it, and
Speaker 2: that versatility is a big part of why Rust has
Speaker 2: become so popular. It lets developers use one language for
Speaker 2: all sorts of projects, which means you don't have to
Speaker 2: keep switching between different languages and ecosystems.
Speaker 1: This has been such an eye opening deep dive. We've
Speaker 1: explored the key features that make RUSS so great for
Speaker 1: web development, walk through building a real world project, and
Speaker 1: even touched on its broader applications.
Speaker 2: It's been a pleasure exploring all this with you. The
Speaker 2: resources you brought the practical rest web projects book and
Speaker 2: Rust documentation. They've given us a really thorough and insightful
Speaker 2: look at what Rust can do.
Speaker 1: I think our listener now has a much better understanding
Speaker 1: of why Rust is making such a splash in the
Speaker 1: tech world. It's not just a language, it's a whole
Speaker 1: new way of thinking about software with a focus on safety, performance,
Speaker 1: and reliability.
Speaker 2: Absolutely, Rust represents a significant step forward in software engineering.
Speaker 2: It gives developers the power to build applications that are
Speaker 2: not just efficient, but also really robust and secure.
Speaker 1: So to our listener out there, we encourage you to
Speaker 1: give Rust a try and explore its growing ecosystem. Whether
Speaker 1: you're building web apps, command line tools, or exploring other
Speaker 1: areas of software development, Rust has something to offer, and
Speaker 1: who knows, maybe you'll be the one to create the
Speaker 1: next big thing, the next cat deck sensation. Keep learning,
Speaker 1: keep experimenting, and until next time, happy coding.
