Rust is a systems programming language focused on three goals: safety,
speed, and concurrency. It maintains these goals without having a
garbage collector, making it a useful language for a number of use
cases other languages are not good at: embedding in other languages,
programs with specific space and time requirements, and writing
low-level code, like device drivers and operating systems. It improves
on current languages targeting this space by having a number of
compile-time safety checks that produce no runtime overhead, while
eliminating all data races. Rust also aims to achieve "zero-cost
abstractions", even though some of these abstractions feel like those
of a high-level language. Even then, Rust still allows precise control
like a low-level language would.
