Struct RetransmissionState 

pub struct RetransmissionState { /* private fields */ }

Stores the current (re)transmission state for the current message and implements the exponential backoff strategy for retransmissions

Implementations

impl RetransmissionState

pub fn new(transmission_parameters: TransmissionParameters, random: f32) -> Self

Initializes this RetransmissionState with retransmission_counter set to None. This assumes that the state is initialized from one of the schedule_ methods which can not actually transmit anything but only trigger an internal state change which requires that the first message is sent in the next process_ invocation.

random must be a random value between 0 and 1.

pub fn retransmit_required( &mut self, now: Instant, ) -> Result<bool, RetransmissionTimeout>

Returns if a retransmission is required, we should keep waiting or if the whole transmission has timed out. Returns:

• Some(true) if a retransmission should happen
• Some(false) if we should keep waiting
• Err(Error::Timeout) if the transmission (with retransmissions) has timed out

If a retransmission is required, this will increase the internal retransmission timer so this assumes that the retransmission will be triggered.
