Rust is a system programming language that focuses on security, especially concurrency security, and supports functional, imperative and generic programming paradigms. Rust is syntactically similar to C++, but the designers want to provide better memory security while ensuring performance. Rust was originally designed and created by Graydon Hoare of the Mozilla Research Institute, and then gradually perfected with the contributions of Dave Herman, Brendan Eich and many others. The designers of Rust optimized the Rust language and Rust compiler through their experience in developing the Servo website browser layout engine.

The Rust compiler is free and open source software under the dual agreement declaration of MIT License and Apache License 2.0. Rust has been crowned the "favorite programming language" project surveyed by Stack Overflow developers for the fourth year in a row (2016, 2017, 2018, 2019).
