Web Assembly: Rust has a great Web Assembly story.Andrew Gallant’s blog post on the subject is a great overview: Error Handling in Rust: Rust has an error handling mechanism that may be unfamiliar to you if you have a C/C++/C# background.Once you have a solid grasp of the above, exploring the world of unsafe Rust will solidify your knowledge of safe Rust even more:.The std lib docs are very accessible and link directly to the source code:.For those who need linked lists in their lives:.Rustlings: Similar to Rust by Example but in a console ( ).

Rust by Example: Go through Rust with code exercises ( ).Therefore, in general, most people find it preferable to read the books (at least the first halves) before trying to build anything complex in Rust. Rust is a particular language that works best when you work with how it wants you to do things. Programming Rust by Jim Blandy and Jason Orendorff:.

It very well could be that you're trying to solve your problem in a way that goes against how Rust wants you to work. If you find yourself struggling hard with the borrow checker, seek help. Once this happens, then you can expand to more real world projects. The generally recommended path is to start by reading the books, and doing small coding exercises until the rules around borrow checking become intuitive. The best way to learn Rust is to embrace its best practices and see where that takes you. Rust is not C or C++ so the way your accustomed to do things in those languages might not work in Rust. | - immutable borrow later used hereįor more information about this error, try `rustc -explain E0502`.The following is a list of resources for learning Rust as well as tips and tricks for learning the language faster. 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.
