Struct StallWatchdog 

pub struct StallWatchdog { /* private fields */ }

A running watchdog. Dropping it stops and joins the thread.

Implementations

impl StallWatchdog

pub fn spawn( name: &str, config: StallConfig, ping: impl Fn(Ack) -> Result<(), String> + Send + 'static, on_event: impl Fn(StallEvent) + Send + 'static, ) -> Result<Self>

Start watching. ping must hand the Ack to the target without blocking on it (enqueue and return); on_event runs on the watchdog thread, so keep it short and lock-free (log, flip an atomic, spawn work).

pub fn stop(&mut self)

Stop and join. Idempotent.

Trait Implementations

impl Drop for StallWatchdog

fn drop(&mut self)

Executes the destructor for this type.

fn pin_drop(self: Pin<&mut Self>)

🔬This is a nightly-only experimental API. (pin_ergonomics)

Execute the destructor for this type, but different to Drop::drop, it requires self to be pinned.
