//! Crate ruma-api-macros provides a procedural macro for easily generating
//! [ruma-api]-compatible endpoints.
//!
//! This crate should never be used directly; instead, use it through the
//! re-exports in ruma-api. Also note that for technical reasons, the
//! `ruma_api!` macro is only documented in ruma-api, not here.
//!
