Struct SentPackets

pub struct SentPackets { /* private fields */ }

Implementations

impl SentPackets

pub fn new(init_seq_num: u16, congestion_ctrl: Controller) -> Self

Note: init_seq_num corresponds to the sequence number just before the sequence number of the first packet to track.

pub fn next_seq_num(&self) -> u16

pub fn ack_num(&self) -> u16

pub fn seq_num_range(&self) -> CircularRangeInclusive

pub fn timeout(&self) -> Duration

pub fn on_timeout(&mut self)

pub fn window(&self) -> u32

pub fn has_unacked_packets(&self) -> bool

pub fn has_lost_packets(&self) -> bool

pub fn lost_packets(&self) -> Vec<(u16, PacketType, Option<Vec<u8>>)>

pub fn on_transmit( &mut self, seq_num: u16, packet_type: PacketType, data: Option<Vec<u8>>, len: u32, now: Instant, )

Panics

Panics if seq_num does not correspond to the next expected packet or a previously sent packet.

Panics if the transmit is not a retransmission and len is greater than the amount of available space in the window.

pub fn on_ack( &mut self, ack_num: u16, selective_ack: Option<&SelectiveAck>, delay: Duration, now: Instant, ) -> Result<(CircularRangeInclusive, Vec<u16>), SentPacketsError>

Handle an ACK for a packet with sequence number ack_num, and an optional selective_ack.

Returns Error, if ack_num is not within the sequence number range of the sent packets.

pub fn last_ack_num(&self) -> Option<u16>

Returns the sequence number of the last (i.e. latest) packet in a contiguous sequence of acknowledged packets.

Returns None if none of the (possibly zero) packets have been acknowledged.
