The biggest advantage of Rust in comparison with other programming languages lies in its security. This is achieved partially through error management. Should an error occur during compilation that cannot be fixed, the appropriately-named “panic!” macro is launched. This shuts down the program and provides an error notification so that no damage can arise.
Rust’s memory management is secure as well. The advantage is that Rust achieves memory safety without a garbage collector. In many programming languages, memory has been a popular point of attack for hackers. When the memory fills up, this can lead to errors in the system, and as a result, a weakness that can be exploited. A “garbage collector” ensures that unnecessary items disappear from memory. This, however, slows the speed of the code when it is run. The Rust compiler makes the “garbage collector” obsolete. Instead, it checks during compilation if there could be an error in the memory.
The strong security features, however, do not exactly come at the cost of performance. Rust is a language for system programming, like C/C++, and also provides the same speed when it is run. On the one hand that has to do with the eschewal of a “garbage collector.” Fast runtime is also ensured by “zero cost abstraction”, which means that you can have the comfort of programming in a language with high levels of abstraction without dealing with declines in performance.
This makes Rust a mix of high-level and low-level programming languages. Like C/C++, Rust is close to the hardware, which ensures high speed, while being just as easy to program as high-level languages.
Both beginners and experienced programmers can get to grips with Rust quickly. In the way it is used, the language is close to established alternatives. A big advantage, however, lies in the amount of effort that went into the design of the error notifications. Where other programming languages only display errors cryptically, Rust provides practical and helpful instructions for how one can fix them.
