Struct PostureWatch 

pub struct PostureWatch { /* private fields */ }

Watch-style subscription to the fleet posture feed — the workers-crate equivalent of a tokio::sync::watch receiver (the crate carries no tokio; this is the parking_lot pattern its other feeds use). One producer (the PostureOwner), many independent consumers: every FleetHost subscribes at boot for the T7 shed trigger, tests subscribe to observe transitions, and the Part B operator channel will drive the owner directly. A consumer sees the latest posture and REAL transitions only — a Held tick or a no-effect retune never raises an edge.

Implementations

impl PostureWatch

pub fn current(&self) -> FleetPosture

The latest posture (reads through — never consumes the edge).

pub fn has_changed(&self) -> bool

Did a transition occur since the last drain? (Does not consume.)

pub fn take_if_changed(&self) -> Option<FleetPosture>

Drain: the posture if a transition occurred since the last drain, else None (consuming the edge — exactly-once per transition).

Trait Implementations

fn fmt(&self, f: &mut Formatter<'_>) -> Result
