pub struct Controller { /* private fields */ }

Implementations

impl Controller

pub fn restart<Pub: ConnectionPublisher>( &mut self, path: Path<'_>, publisher: &mut Pub, )

Restart testing of ECN capability

pub fn on_timeout<Pub: ConnectionPublisher>( &mut self, now: Timestamp, path: Path<'_>, random_generator: &mut dyn Generator, rtt: Duration, publisher: &mut Pub, )

Called when the connection timer expires

pub fn ecn( &mut self, transmission_mode: Mode, now: Timestamp, ) -> ExplicitCongestionNotification

Gets the ECN marking to use on packets sent to the peer

pub fn is_capable(&self) -> bool

Returns true if the path has been determined to be capable of handling ECN marked packets

pub fn validate<Pub: ConnectionPublisher>( &mut self, newly_acked_ecn_counts: EcnCounts, sent_packet_ecn_counts: EcnCounts, baseline_ecn_counts: EcnCounts, ack_frame_ecn_counts: Option<EcnCounts>, now: Timestamp, rtt: Duration, path: Path<'_>, publisher: &mut Pub, ) -> ValidationOutcome

Validate the given EcnCounts, updating the current validation state based on the validation outcome.

• newly_acked_ecn_counts - total ECN counts that were sent on packets newly acknowledged by the peer
• sent_packet_ecn_counts - total ECN counts for all outstanding packets, including those newly acknowledged during this validation
• baseline_ecn_counts - the ECN counts present in the Ack frame the last time ECN counts were processed
• ack_frame_ecn_counts - the ECN counts present in the current Ack frame (if any)
• now - the time the Ack frame was received

pub fn on_packet_sent<Pub: ConnectionPublisher>( &mut self, ecn: ExplicitCongestionNotification, path: Path<'_>, publisher: &mut Pub, )

This method gets called when a packet has been sent

pub fn on_packet_ack( &mut self, time_sent: Timestamp, ecn: ExplicitCongestionNotification, )

This method gets called when a packet delivery got acknowledged

pub fn on_packet_loss<Pub: ConnectionPublisher>( &mut self, time_sent: Timestamp, ecn: ExplicitCongestionNotification, now: Timestamp, path: Path<'_>, publisher: &mut Pub, )

This method gets called when a packet loss is reported
