pub const UFRAME_FIELDS_METADATA_LAYOUT_ID: WireIdentity;Expand description
Metadata layout identity for the canonical UFrame metadata field block carried behind native-prefix framing.
Distinct from NATIVE_PREFIX_METADATA_LAYOUT_ID (the legacy
protobuf-UAttributes block) so that canonical and legacy metadata are
selectable, rejectable profiles: decoding bytes of one profile with the
other codec fails as UWireMetadataError::UnknownMetadataLayoutId,
never as generic malformed metadata.
