Struct StreamNack 

pub struct StreamNack {
    pub stream_id: u64,
    pub next_expected: u64,
    pub missing_bitmap: u64,
}

Receiver → sender retransmit request. Names a stream and the gaps the receiver is missing: next_expected is the lowest sequence not yet received contiguously, and missing_bitmap bit i is set iff next_expected + 1 + i is also still missing. The sender feeds this to ReliableStream::on_nack to pull the matching retransmit descriptors. Carries stream_id itself (rides CONTROL_STREAM_ID like the window grant), so the sender doesn’t depend on the packet header’s stream field.

Fields

stream_id: u64

Stream the NACK applies to.

next_expected: u64

Lowest sequence the receiver has not received contiguously.

missing_bitmap: u64

Bitmap of further missing sequences after next_expected.

Implementations

impl StreamNack

pub fn encode(&self) -> [u8; 24]

Encode to a fixed 24-byte buffer.

pub fn decode(data: &[u8]) -> Result<Self, StreamWindowCodecError>

Decode a 24-byte message. Errors on truncated / oversize input.

Trait Implementations

impl Clone for StreamNack

fn clone(&self) -> StreamNack

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Copy for StreamNack

impl Debug for StreamNack

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

Formats the value using the given formatter.

impl Eq for StreamNack

impl PartialEq for StreamNack

fn eq(&self, other: &StreamNack) -> 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.
