Struct DatagramStatusHeader 

pub struct DatagramStatusHeader {
    pub track_alias: VarInt,
    pub group_id: VarInt,
    pub object_id: VarInt,
    pub publisher_priority: u8,
    pub extension_headers_length: VarInt,
    pub extensions: Vec<u8>,
    pub object_status: ObjectStatus,
}

Datagram status header (draft-11, types 0x02/0x03).

Fields

track_alias: VarInt

Track alias identifying the subscription.

group_id: VarInt

Group identifier.

object_id: VarInt

Object identifier within the group.

publisher_priority: u8

Publisher priority for delivery ordering.

extension_headers_length: VarInt

Total byte length of extension headers (0 for type 0x02).

extensions: Vec<u8>

Raw extension bytes.

object_status: ObjectStatus

Object status code.

Implementations

impl DatagramStatusHeader

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

Encode the datagram status header (no extensions).

pub fn encode_checked(&self, buf: &mut impl BufMut) -> Result<(), CodecError>

Encode the status datagram header, refusing an extension block this framing cannot carry.

The same one-sided rule the payload-bearing header obeys, and the same reason for it: Self::encode writes the framing without a block, so bytes held here would be dropped rather than written.

Errors

CodecError::InvalidField if the value carries extension headers.

pub fn encode_with_extensions( &self, has_extensions: bool, buf: &mut impl BufMut, )

Encode the datagram status header with extensions control.

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

Decode a datagram status header (no extensions).

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

Decode a datagram status header with extensions control.
