Struct DatagramHeader 

pub struct DatagramHeader {
    pub datagram_type: u8,
    pub track_alias: VarInt,
    pub group_id: VarInt,
    pub object_id: VarInt,
    pub publisher_priority: u8,
    pub extension_headers: Vec<u8>,
    pub object_status: Option<VarInt>,
}

Datagram header for draft-15.

The datagram_type byte encodes flags:

• 0x02: end-of-group
• 0x04: no object_id (object_id = 0 implied)
• 0x20: status datagram (carries object_status instead of payload)

Fields

datagram_type: u8

Raw datagram-type byte encoding flags + kind.

track_alias: VarInt

Track alias identifying the track.

group_id: VarInt

Group ID for the contained object.

object_id: VarInt

Object ID (zero when the no-object-id flag is set).

publisher_priority: u8

Publisher priority.

extension_headers: Vec<u8>

Opaque extension-headers blob (only when the 0x01 flag is set).

object_status: Option<VarInt>

Object status (only when the 0x20 status flag is set).

Implementations

impl DatagramHeader

pub fn has_object_id(&self) -> bool

Whether the datagram carries an explicit object_id.

pub fn is_end_of_group(&self) -> bool

Whether this datagram marks the end of its group.

pub fn is_status(&self) -> bool

Whether this datagram carries an object_status instead of payload.

pub fn has_extensions(&self) -> bool

Whether this datagram carries extension headers.

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

Encode the datagram header to buf.

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

Decode a datagram header from buf.

Trait Implementations

impl Clone for DatagramHeader

fn clone(&self) -> DatagramHeader

Returns a duplicate of the value.

fn clone_from(&mut self, source: &Self)

Performs copy-assignment from source.

impl Debug for DatagramHeader

fn fmt(&self, f: &mut Formatter<'_>) -> Result

Formats the value using the given formatter.

impl Eq for DatagramHeader

impl PartialEq for DatagramHeader

fn eq(&self, other: &DatagramHeader) -> bool

Tests for self and other values to be equal, and is used by ==.

fn ne(&self, other: &Rhs) -> bool

Tests for !=. The default implementation is almost always sufficient, and should not be overridden without very good reason.
