Enum StreamType 

#[repr(u64)]
pub enum StreamType {
    Datagram = 1,
    DatagramStatus = 2,
    Subgroup = 4,
    Fetch = 5,
}

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

The draft keeps unidirectional stream types and datagram types in different tables and different number spaces: SUBGROUP_HEADER and FETCH_HEADER name unidirectional streams, OBJECT_DATAGRAM and OBJECT_DATAGRAM_STATUS name datagrams. The numbers happen not to collide on this draft, which is what lets one enum hold all four.

StreamType::from_id therefore answers across both tables and cannot say which one a value came from, which makes it the wrong question to ask about a stream or a datagram in hand. stream_type_error and datagram_type_error ask it per table, and the difference is not cosmetic: a value assigned in the other table is unknown in this one, and this draft answers an unknown type by ending the session.

Variants

Datagram = 1

Datagram with payload (0x01).

DatagramStatus = 2

Datagram with status only, no payload (0x02).

Subgroup = 4

Subgroup stream type (0x04).

Fetch = 5

Fetch stream type (0x05).
