Struct Ladder 

pub struct Ladder { /* private fields */ }

The escalation timer for one teardown. Construct it, send Cancel to the targets, then call Ladder::poll each reactor tick; perform whatever action it returns on the still-live set.

Implementations

impl Ladder

pub fn new(now: Instant, grace: Duration, kill_grace: Duration) -> Ladder

Begin a teardown at now. The caller should immediately send a graceful Cancel to every target (the ladder assumes that happened).

pub fn with_defaults(now: Instant) -> Ladder

pub fn poll( &mut self, now: Instant, all_exited: bool, force: bool, ) -> LadderAction

Decide the next action. all_exited is whether every target has been reaped; force collapses straight to SIGKILL (second signal).

Trait Implementations

impl Debug for Ladder

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

Formats the value using the given formatter.
