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. 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 typin...
One of the biggest benefits of using a systems programming language is the ability to have control over low-level details. Rust gives you the choice of storing data on the stack or on the heap and determines at compile time when memory is no longer needed and can be cleaned up. This allows efficient usage of memory as well as more performant memory...
To many people, Rust is largely viewed as an alternative to other systems programming languages, like C or C++. The biggest benefit Rust can provide compared to these languages is the borrow checker. This is the part of the compiler responsible for ensuring that references do not outlive the data they refer to, and it helps eliminate entire classes...
The Rust experience is larger than a language specification and a compiler; many aspects of creating and maintaining production-quality software are treated as first-class citizens. Multiple concurrent Rust toolchains can be installed and managed via rustup. Rust installations come with Cargo, a command line tool to manage dependencies, run tests, ...
Rust's strong type system and emphasis on memory safety—all enforced at compile time—mean that it's extremely common to get errors when compiling your code. This can be a frustrating feeling for programmers not used to such an opinionated programming language. However, the Rust developers have spent a large amount of time working to improve the err...
Regardless of which programming languages you love now, there's bound to be something that excites or intrigues you about Rust. These are some of the reasons why I and others love Rust so much, and there's many more. If you are looking for extra structure in your project, faster or more efficient code, or the ability to write performant code more q...
