Ask HN: Best way to learn Rust for a C++ programmer?(news.ycombinator.com)

    I'd recommend starting with the Rust book (<https://doc.rust-lang.org/book/>) and doing some of the exercises. It's very beginner-friendly and covers the basics well. After that, check out the Rustonomicon (<https://doc.rust-lang.org/nomicon/>), which goes deeper into the language and its more advanced features.

      I agree, the Rust book is a great resource for beginners. The Rust Fearless Concurrency Guide (<https://rust-lang.github.io/async-book/>) is also worth a look if you're interested in learning about concurrency and parallelism in Rust.

      For those with a C++ background, it might be helpful to know that Rust has excellent C interop (<https://rust-lang.github.io/rust-cheatbook/language-features/ffi.html>). So, if you need to use a C library, you can still do so while writing the rest of your application in Rust.

    Someone mentioned the Rust book, but I think the Rustlings exercises (<https://github.com/rust-lang/rustlings>) are worth mentioning too. They're a collection of small exercises that walk you through many common Rust concepts.

      Thanks for pointing that out! Rustlings is definitely a useful resource for beginners. Just be aware that some of the exercises are a bit outdated and may need to be adjusted to work with the latest version of Rust.

    I think it's also worth noting that the Rust community is incredibly friendly and welcoming to newcomers. If you're ever stuck or have any questions, don't hesitate to ask for help on the Rust user forums (<https://users.rust-lang.org/>) or on IRC.

    Another great resource is the Rust subreddit (<https://www.reddit.com/r/rust/>). There are a lot of knowledgeable people there who are willing to help out and answer questions. Just be sure to search for existing answers before creating a new post.

    If you're looking for real-world Rust practice, check out the Rust Jobs board (<https://www.rust-jobs.com/>) and see if there are any projects that interest you. Contributing to open-source projects is also a great way to learn the language and build your skills.

    • username9 1 year ago | next

      Thanks for the suggestion! I've been looking for a way to get some practical Rust experience, and contributing to an open-source project seems like a great way to do that. Do you have any recommendations for good projects to start with?

      • username10 1 year ago | next

        @username9 I'd recommend checking out the Awesome Rust repository (<https://github.com/rust-unofficial/awesome-rust>). It's a curated list of Rust projects, libraries, and resources, and it's a great place to find projects to work on.

  • username11 1 year ago | prev | next

    I'd also recommend watching some Rust videos on YouTube. I've learned a lot from channels like the Rust Programming Language (<https://www.youtube.com/channel/UCr5EWG5KjYF-LGnFWQZWcww>) and Rust in the Real World (<https://www.youtube.com/channel/UCDqRuAtJNof1flm4nTtnscA>).

    Finally, don't be afraid to make mistakes. Rust has a strong focus on compile-time safety, which means you'll catch a lot of errors at compile time instead of at runtime. This can be frustrating at first, but it's ultimately a good thing, and it will help you write better code in the long run.
