Struct SubgroupHeader 

pub struct SubgroupHeader {
    pub track_alias: VarInt,
    pub group_id: VarInt,
    pub subgroup_id: VarInt,
    pub publisher_priority: u8,
}

Subgroup stream header (follows the stream type varint).

Fields

track_alias: VarInt

Track alias identifying the subscription.

group_id: VarInt

Group identifier.

subgroup_id: VarInt

Subgroup identifier within the group.

publisher_priority: u8

Publisher priority for delivery ordering.

Implementations

impl SubgroupHeader

pub fn encode_stream(&self, buf: &mut impl BufMut)

Encode a subgroup stream header including its leading stream-type field, so the bytes form the start of a data stream a peer can read.

Self::encode writes the body alone, which is what a caller wants once the stream is already open and what a caller must not use for its first write.

pub fn encode(&self, buf: &mut impl BufMut)

Encode the subgroup header into the buffer.

pub fn decode(buf: &mut impl Buf) -> Result<Self, CodecError>

Decode a subgroup header from the buffer.

pub fn decode_stream(buf: &mut impl Buf) -> Result<Self, CodecError>

Decode a subgroup header from the start of a data stream, consuming the leading stream type varint.

Errors with CodecError::UnknownStreamType when the leading type is not one this draft’s stream table assigns, and with CodecError::InvalidField when it is the other assigned type — a stream this reader cannot read, but not one the draft asks a session to be closed over.
