Module data_stream 

Draft-09 data stream header encoding and decoding.

Changes from draft-08:

• extension_count → extension_headers_length (byte length, not count)
• Datagram (0x01): no payload_length or object_status; payload is remaining bytes
• DatagramStatus (0x02): gains extension_headers_length field

Structs

DatagramHeader

Datagram header with payload (draft-09, type 0x01).

DatagramStatusHeader

Datagram status header (draft-09, type 0x02).

FetchHeader

Fetch stream header (follows the stream type varint).

FetchObjectHeader

Object within a fetch stream (draft-09).

ObjectHeader

Object within a subgroup stream (draft-09).

SubgroupHeader

Subgroup stream header (follows the stream type varint).

Enums

Datagram

One datagram, of whichever shape its type field names.

StreamType

Every type ID this draft’s data plane assigns, from two separate tables.

Functions

check_end_of_track 🔒

Refuse an end-of-track object that does not end at object zero.

datagram_type_error 🔒

Which failure a leading datagram type that is not one a reader wants is.

encode_extensions 🔒

Encode extension bytes to the buffer (just writes the raw bytes).

read_extension_bytes 🔒

Read byte_len bytes of raw extension data from the buffer.

stream_type_error 🔒

Which failure a leading unidirectional stream type that is not the one a reader wants is.
