Struct FramePacer 

pub struct FramePacer { /* private fields */ }

Available on crate feature transport only.

Frame pacer that controls when frames can be sent.

The pacer ensures:

• Minimum interval between frames (SRTT/2 or 20ms, whichever is greater)
• Collection interval to batch rapid state changes (8ms)
• Delayed ACK to piggyback on data frames (100ms max)
• Frame rate cap at 50 Hz

Implementations

impl FramePacer

pub fn new() -> Self

Create a new frame pacer.

pub fn set_srtt(&mut self, srtt: Duration)

Update the SRTT from the RTT estimator.

pub fn on_state_change(&mut self)

Notify the pacer that local state has changed.

pub fn on_ack_needed(&mut self)

Notify the pacer that we received a frame and should send an ACK.

pub fn on_frame_sent(&mut self)

Notify the pacer that a frame was sent.

pub fn clear_pending(&mut self)

Clear pending state (e.g., after receiving ACK).

pub fn poll(&self) -> PacerAction

Determine what action to take based on current state.

pub fn needs_keepalive(&self, last_received: Instant) -> bool

Check if we should send a keepalive.

pub fn is_connection_dead(&self, last_received: Instant) -> bool

Check if the connection should be considered dead.
