Module concrete 

ConcreteComponent polymorphism contract — canonical home in bb-runtime::concrete. This module re-exports the type for authoring ergonomics so bb_dsl::concrete::ConcreteComponent keeps resolving.

Structs

ComponentHandle

Owned wrapper that travels through the ModelProto → Node pipeline. Carries captured fn pointers + state bytes.

ConstructError

Errors surfaced by ConstructFn.

DependencyDecl

Author-declared sibling dependency at a named slot. Compiler verifies role match; runtime reaches it via RuntimeResourceRef::dependency::<T>(slot).

Enums

ComponentPackage

Component-package origin tag. Surfaces in introspection + telemetry.

RestoreError

Error variants surfaced by ConcreteComponent::restore.

Traits

ConcreteComponent

Polymorphism contract. Implementing this trait IS the registration mechanism — no global registry, no macro required. Serialized state must be self-contained so restore reconstructs without the original Config.

Type Aliases

ConstructFn

Per-type constructor. Downcasts &dyn Any → &Config and calls T::new. Install looks it up by TYPE_NAME.

RestoreFn

Monomorphized T::restore; used by snapshot/resume.

SerializeFn

Monomorphized T::serialize captured at derive-codegen time.
