Rust vs crystal

You often hear about how fast languages like Rust and Go are. People port all kinds of things to Rust to make them faster. It's common to hear about a company porting a Ruby microservice to Go or writing native extensions for a dynamic language in Rust vs crystal for extra performance.

When comparing Crystal and Rust, it's important to understand the key differences between these two languages to determine which one is best suited for a specific project or use case. Memory management : Crystal uses a garbage collector for automatic memory management, while Rust relies on a unique ownership system that ensures memory safety without the need for garbage collection. This gives Rust a performance advantage in situations where strict memory control is crucial. Concurrency model : Rust emphasizes on thread safety with its ownership and borrowing system, making it easier to write concurrent and parallel programs. On the other hand, Crystal provides lightweight fibers for concurrency, which can be more approachable for developers new to concurrent programming. Type system : Crystal features a more conventional object-oriented type system with static typing, similar to languages like Ruby.

I wish Crystal would take off. It has so many things going for it many of them mentioned in the article : performance, useful tooling such as an opinionated formatter, an integrated RSpec-like test framework, a powerful standard library, an awesome type system that gets out of the way most of the time, a familiar syntax. So far I have been building some smaller personal CLI tools and a few web apps with the Lucky framework. Coming from a decade of Ruby, due to the similar syntax and mindset Crystal is my go to for cases where I need performance or runtime-less execution e. Crystal's standard library provided enough functionality for me in the past to get away with only few dependencies per project, which is great for supply chain security and complexity. As a Ruby dev, that Crystal is "close but different" means I know I won't be able to use my Ruby code but at the same time I get too little in return to make it feel worthwhile. For the very rare circumstances where Ruby is too slow for what I need to do, there's usually code in some other language I can wrap in an extension, and that code is far more likely to be C or some other more established language than Crystal. To me Crystal is actually a more polished Ruby implementation. Ruby was my main language for scripting, but I switched to Crystal completely after getting comfortable with it. Now it is really hard to switch back to Ruby. Also, I thing compiled language is the greatest friend for older programmers. Over the time I'm getting more and more sloppy and very often make some typing error.

I often look in dismay at the growing popularity of Go and wonder if Crystal could ever catch up. Really, programming languages are a lot like people in real life For me, Crystal is like the unpopular, down-to-earth nerdy kid, who once you meet him you wonder why he isn't running the whole school — or at least, the nerdy non-mainstream parts of the school where Go and Rust rule supreme. Obviously JavaScript and probably Python are running the show at the top of the hierarchy, wearing their undeserved varsity jackets and cheer-leading uniforms or whatever the modern zoomer equivalent is of this worn-out 90s trope. I really like Crystal.

You often hear about how fast languages like Rust and Go are. People port all kinds of things to Rust to make them faster. It's common to hear about a company porting a Ruby microservice to Go or writing native extensions for a dynamic language in Rust for extra performance. Crystal also compiles your apps into blazing-fast native code, so today I decided to try comparing Rust and Crystal side-by-side in talking to a Redis database. They're CPU-intensive, absolutely, but they're nothing like the workload a typical web app has. The benchmark I went with was to connect to a Redis database and run a bunch of pipelined commands. Pipelining means we're sending all of the commands before reading any of them. Because we're not waiting for the result after sending each command, this drastically reduces the impact that latency has on the benchmark. For example, instead of this sequence:.

Fast, flexible and pragmatic, PHP powers everything from your blog to the most popular websites in the world. Kotlin has a bit of learning curve, so, by the time you can actually use it idiomatically chances are that you will get proficient in Java too. Will it glue them together? By convention, methods that end in a question mark are predicate methods that return a boolean. Familiarity helps implicitness be understood. Hacker News new past comments ask show jobs submit. We have a lot of experience in JavaScript, writing our services in NodeJS allows developers to transition to the back end without any friction, without having to learn a new language. If Crystal gets a good language server, heck yeah I'll roll with it. Might be a reason to choose Rust. The idea was to see if Rust was really the performance trailblazer we all thought it was and it turns out Crystal has just as good, if not way better, performance for cases like this. Absolutely concur. Crystal's standard library provided enough functionality for me in the past to get away with only few dependencies per project, which is great for supply chain security and complexity.

Jun 10, I honestly think it needs better frameworks to draw bigger crowds, and it needs more devs in the community to build and maintain them. All of these are solid options, however considering your expertise currently, I would probably suggest Node. I end up spending more time porting unit tests than porting the underlying code. Alifatisk 10 months ago root parent next [—] Thanks! Crystal core developer speaking: I think this argument is less about the concrete syntactical and semantic similarities to Ruby, but the shared general idea to focus on developer happiness. The only thing RSpec really "adds" is an insane and quirky DSL for the sake of "reading like English", which is a terrible misfeature. Given it took that little, I don't think you need much code in a new language before you have a reasonable starting point as long as you can give examples and document the differences, and then use that on a few large projects that has good test suites, and work through any breakage. For example, code is easy to read, yet still expressive. Go and Rust over Python: Startup and runtime performance Go and Rust over Python: No need to worry about which Python interpreter version is installed on the users' machines. It does not teach you clean programming at all. Crystal Ruby is so much simpler. The world of IT is beautiful. Give an error?
