The Elegant Parser [](https://awesome.re) [<img src="https://avatars.githubusercontent.com/u/26044607" align="right" width="100">](https://github.com/pest-parser/pest/) > A curated list of resources, projects, and tools using or for the pest parser generator in Rust pest is a general purpose parser written in Rust with a focus on accessibility, correctness, and performance. It uses parsing expression grammars (or [PEG](https://en.wikipedia.org/wiki/Parsing_expression_grammar)) as input, which are similar in spirit to regular expressions, but which offer the enhanced expressivity needed to parse complex languages.
