%description
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.
