API reference

The full Rust API reference is generated by rustdoc and published on docs.rs. This site covers concepts and guides; docs.rs is the source of truth for every type, trait, and function signature.

The ruststream command-line tool is the same crate's cli feature, not a separate crate; see the CLI guide.
