aeat.core.resources._keys module

Typed key base models for the resource-management API.

Each ResourceCacheRepository declares its own key model or uses a trivial type for singleton and year-keyed resources. Concrete keys such as ManualKey inherit from TypedResourceKey when the lookup needs multiple fields.

Cache keys are Pydantic v2 models with frozen=True so they are hashable for dict-backed Identity Maps. Singletons use None directly as the key; year-keyed Repositories use bare int values.

class TypedResourceKey(**data)

Bases: BaseModel

Common base for typed Repository keys.

Each ResourceCacheRepository that needs more than None or int as its key inherits from this base and adds its own fields. The frozen=True config makes the model hashable for Identity Map dict use.
