Module metadata 

Stream metadata values and their publication into the runtime claim store.

This module supplies the concrete description of a stream’s identity: StreamMetadata bundles a stream id, its StreamMedia kind, StreamDirection, clock symbol, and buffer policy. RateContract captures the clock-domain/latency/rate agreement two ports must share to connect.

The kernel defines the claim/fact contract and the clock-domain surface; this module supplies the streaming-fabric behavior on top of it. The stream_*_predicate helpers name the predicate symbols, and publish_metadata_claims writes a stream’s metadata into the runtime as public facts so other libraries can query a stream’s shape.

Structs

RateContract

Timing agreement a stream port advertises and must share to connect.

StreamMetadata

Full identity of a stream: id, media kind, direction, clock, and buffer policy.

Enums

StreamDirection

Flow direction of a stream relative to its owner.

StreamMedia

Media kind carried by a stream.

Functions

publish_metadata_claims

Publishes a stream’s metadata into the runtime as public facts about subject.

stream_buffer_predicate

Returns the stream/buffer predicate symbol used for buffer-policy facts.

stream_direction_predicate

Returns the stream/direction predicate symbol used for direction facts.

stream_id_predicate

Returns the stream/id predicate symbol used for stream-identity facts.

stream_media_predicate

Returns the stream/media predicate symbol used for media-kind facts.
