Rust is a new programming language for systems software under development at Mozilla. Rust aims to be safe, concurrent, practical and fast, and accomplishes this through standard techniques such as a type system that enforces memory techniques, but also with more uncommon features such as a typestate system. Particular attention is given to allowing the programmer control over where objects reside in memory and tracking ownership as values move through a program. These features allow Rust’s task and communication system to be expressed completely as a library instead of requiring additional language primitives, simplifying the overall language design and implementation. I’ll be providing a brief overview of the Rust language, and focus on my work implementing the task and communication system this summer.
