Struct WatchdogContext 

pub struct WatchdogContext { /* private fields */ }

Delegated control capability scoped to one exact watchdog work attempt.

Mutation authority expires when the callback completes. Retain the WatchdogRegistration for longer-lived ownership.

Implementations

impl WatchdogContext

pub const fn identity(&self) -> &TimerIdentity

Return the logical timer identity executing this work.

pub fn ensure_scheduled(&self) -> Result<(), TimerError>

Request that the pre-armed cadence successor remain scheduled.

This is idempotent unless it supersedes a nested cancellation request. It never arms an additional Watchdog successor.

pub fn cancel(&self) -> Result<(), TimerError>

Request cancellation while this exact work attempt is active.

Cancellation does not interrupt the current invocation; normal completion clears the already-armed successor when cancellation wins. A retained declaration becomes inactive; a remove-on-stop declaration is removed.
