![]() As a result, Rust programs have extremely low memory usage, especially when compared to garbage-collected alternatives. These allow the compiler to insert instructions to free resources when they go out of scope. ![]() Second, Rust’s type system introduces the concepts of ownership and borrowing. As such, its human-friendly constructs can be optimised away at compile time, leaving behind only machine-friendly instructions in binaries. First, Rust builds on twenty years of cutting-edge research on LLVM. In other languages, pleasant high-level abstractions would incur a significant cost, but in Rust, it is possible to have these benefits and the performance normally reserved for low-level languages, something which is possible for two reasons. Rust’s strict type system helps significantly with this, reducing the time spent chasing bugs with debugging tools to the point that, as Andre Bogus, a maintainer of Rust’s linter puts it, ‘ applications often don’t need debugging in the first place.’ The language provides many high-level abstractions, such as a standard container library, iterators, traits and functional programming style methods, all of which avoid the need to repeat common implementation boilerplate, allowing the developer to focus on implementing useful features. Writing Rust, although daunting given its initial learning curve, is actually quite pleasant. Since memory errors are the source of most security vulnerabilities recently found by Microsoft, Google and Apple, these safety features mean that the language is uniquely placed to help create reliable and secure software. Put simply, if a Rust program passes compilation, memory usage is guaranteed to be safe, resources cannot be used after being released and errors have been handled or acknowledged. It’s no secret that Rust is a secure language, and much of this is down to its expressive type system which allows for rigorous checks during compilation. So how do these make Rust the right choice for you? ![]() Rust is a language with many exciting properties, including excellent security, high-level ergonomics, low-level performance and a superb user experience. Let’s examine why Rust is often a great choice and take a look at how to get started with it on Ubuntu. However, its many high-level rules and abstractions create a steep initial learning curve which can leave the impression that Rust is the preserve of a select few but this couldn’t be any further from the truth. Rust has been the language most loved by developers for the last 8 years and it is seeing increased adoption by software companies of all sizes.
