Enum Acknowledgement

pub enum Acknowledgement {
    Lite(SeqNumber),
    Small(SeqNumber, AckStatistics),
    Full(SeqNumber, AckStatistics, FullAckSeqNumber),
}

Data included in a ACK packet. spec

There are three types of ACK packets:

• Full - includes all the fields
• Lite - no optional fields
• Small - Includes rtt, rtt_variance, and buffer_available

However, these aren’t necessarily clean categories–there may be some amount of overlap so full acks are allowed to have no extra info and short acks are allowed to have all the info

SeqNumber is the packet sequence number that all packets have been received until (excluding)

Variants

Lite(SeqNumber)

Small(SeqNumber, AckStatistics)

Full(SeqNumber, AckStatistics, FullAckSeqNumber)

Implementations

impl Acknowledgement

pub fn ack_number(&self) -> SeqNumber

pub fn full_ack_seq_number(&self) -> Option<FullAckSeqNumber>

pub fn rtt(&self) -> Option<Rtt>

pub fn statistics(&self) -> Option<&AckStatistics>

pub fn serialize(&self, into: &mut impl BufMut)

Trait Implementations

impl Clone for Acknowledgement

fn clone(&self) -> Acknowledgement

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for Acknowledgement

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

Formats the value using the given formatter.

impl PartialEq for Acknowledgement

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