The community developers are always looking for exciting things on Rust, and your contribution will help the community. This is an excellent and creative opportunity to contribute to the Rust ecosystem. In case you are unable to find something suitable, you will have to create it. But the Rust ecosystem is not mature like Go, Python, or Java. The Rust programming language has a lot of high-quality libraries. You may not find the library that you need. Here the LLDB debugger can help with ease. In that case, you do not have to fear as there is an excellent Rust plugin available.įor me, the IntelliJ debugger works fine, but it may get challenging to get details on the variables when they are allocated on the heap. Suppose you are a Java or Kotlin developer and are familiar with IntelliJ IDEA, which is an integrated development environment in Java.

Cargo helps build code, download the libraries that the code depends on, and build those libraries. Rust has some great tools like 'Cargo' which is a Rust dependency manager. So, don't fight the borrow checker, and embrace it :) The tooling is good Personally, it was my case when developing concurrent features on other programming languages like Java and Go. You're probably doing something "wrong" for years without knowing. "Don't fight the borrow checker", spend time to understand why it throws you to error - it's for your good. Rust changes the way we build applications for the better.ĭue to the excellent type system, Rust is safe by design, and it changes the way one builds applications positively. I'd also recommend reading the official book on Rust programming language, which is available at. I'd recommend spending time to dig into crucial concepts like Borrowing, Ownership, and Lifetime to understand Rust better. You should not expect them to be effective in the first month itself. Like other languages, developers new to Rust will take time to learn the concepts, play with code, and be productive. There is a learning curve associated with each programming language. Feedback Don't expect new programmers to be productive in the first month. Rust prevents misuse of threads, which can be frustrating - but for good reasons. However, from my experience, I saw a lot of devs abusing Goroutines (lightweight threads), leading in concurrency issues. What we're doing with Rust could be done with Go. Once it's compiled, it works like a charm. | - immutable borrow later used hereįor more information about this error, try `rustc -explain E0502`.Houston we have a 404 problem :) Credits NASA fn greet_user(name: Option) !", nickname) Here’s an example of a function to greet someone whether or not we know their name if we had forgotten the None case in the match or tried to use name as if it was an always-present String value, the compiler would complain. This prevents occurrences of the dreaded TypeError: Cannot read property 'foo' of null runtime error (or language equivalent), instead promoting it to a compile time error you can resolve before a user ever sees it. Like Haskell and some other modern programming languages, Rust encodes this possibility using an optional type, and the compiler requires you to handle the None case. This means any value may be what it says or nothing, effectively creating a second possible type for every type. Many statically-typed languages have a large asterisk next to them: they allow for the concept of NULL. This isn’t to say that all static type systems are equivalent. Statically-typed languages allow for compiler-checked constraints on the data and its behavior, alleviating cognitive overhead and misunderstandings. You only need to look at the rise of languages like TypeScript or features like Python’s type hints as people have become frustrated with the current state of dynamic typing in today’s larger codebases. The arguments between programmers who prefer dynamic versus static type systems are likely to endure for decades more, but it’s hard to argue about the benefits of static types.
It’s not all roses in Rust-land, so I talk about the downsides, too. I’ll show a sample of what Rust offers to users of other programming languages and what the current ecosystem looks like. The short answer is that Rust solves pain points present in many other languages, providing a solid step forward with a limited number of downsides. However, the roughly 97% of survey respondents who haven’t used Rust may wonder, “What’s the deal with Rust?” Rust has been Stack Overflow’s most loved language for four years in a row, indicating that many of those who have had the opportunity to use Rust have fallen in love with it.
