rust-peg
A Parsing Expression Grammar (PEG) parser generator for Rust that builds recursive descent parsers from concise grammar definitions.
What is rust-peg?
rust-peg is a parser generator for Rust that allows developers to define parsers using Parsing Expression Grammars (PEGs) through a convenient macro. It solves the problem of writing reliable and maintainable parsers by generating recursive descent parsers from concise grammar definitions, eliminating much of the boilerplate typically associated with parser implementation.
Rust developers who need to parse custom file formats, domain-specific languages, or complex data structures and want a type-safe, embeddable parser generator with good error reporting.
Developers choose rust-peg for its simplicity, flexibility in input types, helpful error messages, and the ability to embed Rust code directly within grammar rules while benefiting from PEG's deterministic parsing behavior and precedence climbing for expressions.
