Trait DeliverySignal 

Source 
pub trait DeliverySignal {
    // Required methods
    fn poll_delivered(&mut self) -> Delivered;
    fn rtt_hint(&self) -> Option<Duration>;
}
Expand description

The honest clock. Reports how many in-flight bytes were delivered or lost since last polled.

Impl A (preferred): reliable-mode frame acknowledgements — an acked frame retires its bytes as acked_bytes; a frame whose retransmissions are exhausted retires as lost_bytes.

Impl B: application-verified return bytes (e.g. a loopback echo the caller can checksum).

Required Methods§

Source

fn poll_delivered(&mut self) -> Delivered

Non-blocking: returns bytes delivered/lost since the previous call (zeroes if none).

Source

fn rtt_hint(&self) -> Option<Duration>

Best-effort round-trip delivery latency, used to (re)seed the BDP ceiling. None if unknown.

Dyn Compatibility§

This trait is dyn compatible.

In older versions of Rust, dyn compatibility was called "object safety".
