The tcl_derive crate provides the proc-macro implementation for the tcl crate.

1. The #[proc] attribute to get a Rust fn ready for registering as a Tcl command.

2. The tclfn!{} macro to define a Rust fn and register it as a Tcl command.

3. The tclosure!{} macro to define a Rust closure and register it as a Tcl command.

See tcl crate's doc for more.
