Rust Alternatives
Rust is described as 'Multi-paradigm, general-purpose programming language that emphasizes performance, type safety, and concurrency. It enforces memory safety—meaning that all references point to valid memory—without a garbage collector' and is a very popular programming language in the development category. There are more than 25 alternatives to Rust for a variety of platforms, including Linux, Mac, Windows, BSD and Self-Hosted apps. The best Rust alternative is Python, which is both free and Open Source. Other great apps like Rust are C++, C (programming language), Go (Programming Language) and C#.
