nom

Returns slices of input data without copying, minimizing memory overhead for binary and text formats, as highlighted in the README's technical features.

Handles partial data gracefully, making it suitable for network protocols and large files where data arrives in chunks, ensuring deterministic parsing.

Benchmarks show it often outperforms other parser combinator libraries, regex engines, and even handwritten C parsers, prioritizing speed without sacrificing safety.

Leverages Rust's memory safety and type system; fuzzing has found no flaws in nom itself, reducing vulnerabilities like buffer overflows.
