Struct SchedulerHandle 

pub struct SchedulerHandle { /* private fields */ }

Owns running scheduler loops and exposes their typed failures.

The handle buffers at most 256 undrained errors. When the buffer is full, newer errors are dropped, counted by Self::dropped_errors and emitted as tracing warnings. Drain Self::next_error to observe every failure.

Implementations

impl SchedulerHandle

pub async fn next_error(&mut self) -> Option<SchedulerError>

Waits for the next timeout, panic, or runtime failure reported by a task.

pub fn try_next_error(&mut self) -> Option<SchedulerError>

Returns a pending scheduler failure without waiting.

pub fn dropped_errors(&self) -> u64

Returns how many failures were dropped because the buffer was full.

pub async fn shutdown(self) -> Result<(), SchedulerError>

Gracefully stops task loops, aborting any current handler execution.

Errors

Returns the first reported task failure, or a typed loop join failure.

Trait Implementations

impl Drop for SchedulerHandle

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.
