nom is a parser combinator library for Rust that lets you build safe, fast, zero-copy parsers for binary and text formats using combinators, macros, and traits. It leverages Rust's strong typing and memory safety to produce correct parsers without sacrificing speed or memory efficiency.

Use cases

• parse binary file formats in rust
• write a text format parser
• build a programming language parser
• parse streaming data incrementally
• parse protocols or byte arrays
• create a grammar-based parser without heavy dependencies

When to choose

• you need fast, zero-copy parsing in Rust
• you're parsing binary formats or byte streams
• you want composable parser building blocks instead of a grammar generator
• memory safety and correctness matter

When to avoid

• you prefer declarative grammar tools like LALRPOP or pest
• you need a full compiler frontend with AST tooling
• you're not working in Rust
