Optional ReadonlyboundedWhether the stream has a natural end. Defaults to true; false marks
a live source that runs until end-of-stream or a stop. Always declared,
never inferred from a missing size.
ReadonlykindOptional ReadonlypayloadThe payload type ID carried by this stream. Defaults to BYTES_PAYLOAD_TYPE. Confirmed by the open handle, since some sources only know it after connecting.
Readonlystream
A handle to a readable or writable stream of a single, declared PayloadKind - homogeneous, so consumers never need to test each item's kind. Plus optional capability methods for providers/decorators that support more than plain sequential read/write - see the capability interfaces and
is*guards incapability/.
