Module registries 

Trait-based registries for schema resolution and endpoint routing.

These abstractions provide functional local defaults (in-memory HashMaps) that validate structural correctness within UAR’s own scope. External backends (Redis, etcd, external schema registries) can be plugged in by implementing the same traits.

Structs

EndpointBinding

Binding between an A2A endpoint ID and its routing target.

InMemoryEndpointRegistry

In-memory endpoint registry backed by a HashMap.

InMemorySchemaRegistry

In-memory schema registry backed by a HashMap.

Traits

EndpointRegistry
