Struct glommio::DefaultStallDetectionHandler

pub struct DefaultStallDetectionHandler {}

Default settings for signal number, threshold and stall handler. By default, the threshold to consider a task queue stalled is set to 10ms over the expected run time. The default handler will log a stack trace of the currently executing task queue. The default signal number is nix::libc::SIGUSR1.

Trait Implementations

impl Debug for DefaultStallDetectionHandler

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

Formats the value using the given formatter.

impl StallDetectionHandler for DefaultStallDetectionHandler

fn threshold( &self, _queue_handle: TaskQueueHandle, _max_expected_runtime: Duration ) -> Option<Duration>

How far past the preemption timer should qualify as a stall If None is returned, don’t use the stall detector for this task queue. The default implementation considers anything running 10ms over expected runtime to be stalling the reactor.

fn signal(&self) -> u8

What signal number to use; see values in libc::SIG*. The default is nix::libc::SIGUSR1.

fn stall(&self, detection: StallDetection<'_>)

Handler called when a task exceeds its budget. The default implementation is to log a warning.
