System Documentation

What problem does it solve?

Formats generated Rust code by turning syn::File ASTs into readable source using prettyplease::unparse, avoiding external rustfmt tooling and ensuring stable output for code generated at build time or by macros.

Core Features & Use Cases

  • Library-based formatting: format in-process without spawning a formatter binary.
  • AST-focused: operates on syn::File and handles common generated-code scenarios (proc macros, build scripts, code generators).
  • Deterministic output: yields consistent formatting suitable for reproducible code generation.

Quick Start

Use prettyplease to format a syn::File AST into readable Rust source.
