Rust vs crystal

I often look in dismay at the growing popularity of Go and wonder if Crystal could ever catch up. Really, rust vs crystal, programming languages are a lot like people in real life

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.

Rust vs crystal

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. In contrast, Rust employs a strong static type system with lifetimes and borrowing rules, providing strict compile-time checks for memory safety and thread concurrency. Error handling : Rust uses the Result type and the Option type to handle errors and nullable values, ensuring that errors are handled explicitly by the developer. In comparison, Crystal uses exceptions for error handling, which can simplify code but may also lead to unexpected behavior if not properly managed. Community and ecosystem : Rust has a larger and more mature ecosystem with established libraries and tools for various use cases, making it easier to find support and resources for development.

I will highly recommend Kotlin.

Crystal Ruby is so much simpler. If you want to get stuff done quickly, and still have time to live your life, use Crystal. Here is the full code and output on Rosettacode. I just saw I could simplify the code, and for Crystal, make it faster too. The times are literally the same now, and almost 2.

Read original article here. 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.

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.

I also considered Rust, but learning curve of it is much higher than in Golang. I suppose it is to be expected that Crystal and Rust have comparable performance for such an example. That's a 'yikes' of a language that no one should ever use. It's at that magical stage of an open source community where people are extremely competent and responsive, but not yet? What's your largest Crystal code base? Though it's unlikely to give a 2x improvement. Concurrency model : Rust emphasizes on thread safety with its ownership and borrowing system, making it easier to write concurrent and parallel programs. Walrus operator in Python. Apples and oranges. Python still seems to have funding issues. Personally I use Rust for a lot of things, even though I'm more productive in other languages, but sometimes it's just a really good fit for the problem. I was thinking about adding a new technology to my current stack Ruby and JavaScript. Rust is not easy to learn as a beginner. I often just fired up IRB the repl and guessed what function names I could use on a given object and it worked. Mawr 10 months ago parent prev next [—].

Do you love Ruby? Do you wish there was a better version of Ruby with blazing-fast performance like C? Well, your prayers have been answered.

What tools integrate with Rust? I don't need group approval for this to be the case. Apples-and-Oranges comparison: I've turned a nodejs-based app that used roughly mb memory into an executable using 12mb. They're CPU-intensive, absolutely, but they're nothing like the workload a typical web app has. Crystal, while growing rapidly, has a smaller community and fewer libraries available, which can impact the ease of development in certain scenarios. It's just very fast across the board. But yeah, it has "if", "class" and a not-great multithreading story like Python. You can use Kotlin for a lot of application types. The latter has also not leaked any substantial amount of memory after running for 5 months straight now still says 12mb so, take that as you wish In that case, it's effective to write prototype in an easy language like Python, and rewrite it in a hard language. Crystal has been going on for years and there is still no major support, it won't change, basically if you're a new lanague you have a couple of years after that you just missed the train. Charles Severance called Programming for everybody, check it out :. The original comment claimed a language needs first class Windows support at a minimum to take off. Try it, it's very programmer-friendly. Coming from other languages, the developer experience would arguably be different.
