Implementations

impl DelayDoState

pub fn is_transient(self) -> bool

True where the state’s when clauses are exhaustive, so SNL leaves it on the same evaluation that entered it rather than waiting for a new event: init’s pvConnectCount() == pvAssignCount() (delayDo.st:35), maybeStandby’s standby/active/!standby triple (:58-74), maybeWait’s active/efTest/!efTest triple (:121-138), and action’s bare when () (:201). A runner must keep stepping while this holds.

pub fn is_published(self) -> bool

True where entering the state writes its name to {P}{R}:state. maybeStandby and maybeWait are the two exceptions, and deliberately so — “the state doesn’t last long enough” (delayDo.st:51-52, :112-113) is why their PVPUTSTR calls are commented out upstream.
