zesterer/chumsky ★ 4538 212 APPLICATION

Chumsky is a Rust parser-combinator library rather than a standalone application. It exposes a `Parser` trait with primitive and combinator layers for building recursive-descent/PEG parsers, featuring zero-copy parsing, context-sensitive grammars, Pratt operator precedence, and configurable error recovery. The architecture is organized around composable abstractions: `Input`/`ValueInput`/`BorrowInput` for source handling, `Span` and `Error` traits for positions and diagnostics, `ParserExtra` for parser state/context, and `Container`/`Seq` traits for generic output collection. The main entry points are the public API in `src/lib.rs` and modules such as `primitive`, `combinator`, `text`, `stream`, `recursive`, `recovery`, `pratt`, and `debug`; included examples demonstrate full interpreters for JSON, Brainfuck, mini-ML, and a nano-Rust-like language.
