Struct ThreadLockupDetector 

pub struct ThreadLockupDetector;

Implementations

impl ThreadLockupDetector

pub fn get_long_running_threads( threshold: MonotonicDuration, ) -> Vec<ThreadLockupInfo>

Iterates over the registry, finds threads that have been running an operation for at least the threshold, and returns their ThreadLockupInfo.

Operations are timestamped by the first call that observes them, not when they start: an operation is reported once the call that first observed it is at least threshold old. When called periodically, this delays reports by at most one period.

pub fn track() -> LockupDetectorGuard

Starts tracking the current operation on the current thread. Returns a guard that stops tracking when dropped.

pub fn pause_tracking() -> LockupDetectorWaitingGuard

Pauses tracking for the current operation on the current thread. Returns a guard that resumes tracking when dropped.

pub fn track_future<F>(inner: F) -> LockupDetectorFuture<F>

Wraps a future to track its execution when polled.

pub fn tracked_channel<T>() -> (Sender<T>, LockupDetectorReceiver<T>)

Creates a channel where the receiver pauses tracking while waiting for messages.

pub fn active_rcu_read_locks<F>(check: F)

where F: FnMut(&Thread, Koid, u8),
