What is Rust and why is it useful?

Rust is a programming language that was created to be fast, efficient, and provide low-level control over a computer's hardware, while also being safe from memory-related errors that can cause crashes or security vulnerabilities. It is designed for systems programming, which means it can be used to create operating systems, device drivers, embedded systems, and other low-level software that needs to interact directly with a computer's hardware. The key features of Rust are its focus on safety and reliability, and its ability to write code that runs as fast as C or C++. Rust's ownership model and borrow checker help prevent common bugs and security vulnerabilities that may occur in other languages.
