concinnity-core 0.18.65

//! Every component type the runtime can store: the ones an authored world
//! declares and the ones only the runtime mints, plus the resources the cook
//! compiles into the blob's resource stream.
//!
//! An authored component's data schema lives in concinnity-asset, so those
//! arrive here as re-exports; the modules defined here are the runtime-only
//! components plus the authored ones that need more than plain data -- a
//! runtime struct distinct from its authored args, an extension trait, a
//! build-time `SourceBacked` binding, or a helper the generated `Component`
//! impl can't express. Most components are pure data whose impl is generated
//! from the registry (see `cn_impl_components!` in `ecs::registry`).
//!
//! The authoring-only vocabulary -- the types a world declares and the cook
//! expands away, and the authored args schemas that diverge from the component
//! they bake into -- is not named here. It lives in
//! [`concinnity_asset::cook`], and the registry half of it in
//! `concinnity_world::registry::build_only`.
//!
//! Systems are not components: every system is internal code (see
//! `World::start`), driven by the presence of the components defined here. The
//! client re-exports this module under the historical `crate::components::*`
//! paths.

// Component data types.
