impl Controller for Cubic

source

fn on_ack(
    &mut self,
    now: Instant,
    sent: Instant,
    bytes: u64,
    app_limited: bool,
    rtt: &RttEstimator

fn on_congestion_event(
    &mut self,
    now: Instant,
    sent: Instant,
    is_persistent_congestion: bool,
    _lost_bytes: u64
)

Packets were deemed lost or marked congested Read more

source

fn window(&self) -> u64

Number of ack-eliciting bytes that may be in flight

source

fn clone_box(&self) -> Box<dyn Controller + 'static, Global>

Duplicate the controller’s state

source

fn initial_window(&self) -> u64

Initial congestion window

source

fn into_any(self: Box<Cubic, Global>) -> Box<dyn Any + 'static, Global>

Returns Self for use in down-casting to extract implementation details

source

fn on_sent(&mut self, now: Instant, bytes: u64, last_packet_number: u64)

One or more packets were just sent

source

fn on_end_acks(
 &mut self,
 now: Instant,
 in_flight: u64,
 app_limited: bool,
 largest_packet_num_acked: Option<u64>
)

Packets are acked in batches, all with the same now argument. This indicates one of those batches has completed.
