Syn is a library for parsing Rust code, largely geared toward use in procedural macros but generally applicable as a Rust parser outside of that too.

Syn was originally a sidequest on the effort to making Serde's derive macros work on stable Rust in 2016, but has since taken off as a foundational library in its own right. These days it appears in support of diverse use cases like:

• convenient interop between Rust-based Wasm modules and JavaScript,
• easy command line interfaces,
• a polished async experience, and
• [a concurrency framework for embedded real time systems][rtfm].
