Struct SpinBitState

Source

pub struct SpinBitState { /* private fields */ }

Expand description

Spin bit state for passive RTT estimation.

Uses asymmetric roles (initiator/responder) per the MMP design:

Initiator: flips spin value on each received frame; measures RTT from edge-to-edge intervals.
Responder: copies received spin bit into outgoing frames, with a counter guard to filter reordered frames.

Implementations§

Source §

impl SpinBitState

Source

pub fn new(is_initiator: bool) -> Self

Source

pub fn is_initiator(&self) -> bool

Check if this is the spin bit initiator.

Source

pub fn tx_bit(&self) -> bool

Get the spin bit value to set on an outgoing frame.

Source

pub fn rx_observe( &mut self, received_bit: bool, counter: u64, now: Instant, ) -> Option<Duration>

Process a received frame’s spin bit.

Returns an RTT sample duration if an edge was detected (initiator only).
