`unienv_interface.space.metadata`¶

Read-only, JSON-serializable metadata attached to spaces (see Space.metadata).

EMPTY_METADATA `module-attribute` ¶

EMPTY_METADATA = SpaceMetadata()

SpaceMetadata ¶

SpaceMetadata(data: Optional[Mapping[str, Any]] = None)

Bases: Mapping

Immutable, JSON-serializable str-keyed mapping describing a space.

Created from any mapping of JSON data (validated and deep-copied); nested mappings are frozen into SpaceMetadata and lists into tuples. Compares equal to plain mappings with the same content (lists and tuples are interchangeable). to_dict() returns a plain, mutable JSON copy.

get ¶

get(key: str, default: Any = None) -> Any

to_dict ¶

to_dict() -> Dict[str, Any]

Return a plain (mutable) dict / list copy, as written to JSON.

coerce_metadata ¶

coerce_metadata(metadata: Optional[Mapping[str, Any]]) -> SpaceMetadata

metadata as a SpaceMetadata (validated and copied unless it already is one).
