%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.
