Procedural macros for the Actus controller system: the #[controller]
attribute and the app_routes! macro. (The routes! macro that appears
inside a #[controller] impl is a macro_rules! in actus-controller;
#[controller] consumes the block it produces.)
This crate is an implementation detail — depend on actus (or
actus-controller) and use the macros through their prelude re-exports
rather than depending on this crate directly.
Supports HTTP verb constraints, path parameters (including a trailing
{...rest}), strict/lax parameter modes, prepare hooks, per-controller
rate_limit / max_body_bytes, and per-route docs sourced from each handler's
/// comment.
