Struct StoredTask 

pub struct StoredTask { /* private fields */ }

A type-erased future stored in the runtime.

This type holds a boxed future that has been wrapped to send its result through a oneshot channel. The actual output type is erased to allow storing heterogeneous futures in a single collection.

Implementations

impl StoredTask

pub fn new<F>(future: F) -> Self

where F: Future<Output = Outcome<(), ()>> + Send + 'static,

Creates a new stored task from a future.

The future should already be wrapped to handle its result (typically by sending through a oneshot channel).

pub fn new_with_id<F>(future: F, task_id: TaskId) -> Self

where F: Future<Output = Outcome<(), ()>> + Send + 'static,

Creates a new stored task from a future with a task ID.

The task ID is used for tracing poll events.

pub fn set_task_id(&mut self, task_id: TaskId)

Sets the task ID for tracing.

pub fn set_polls_remaining(&mut self, remaining: u32)

Sets the budget polls remaining for the next poll trace.

The executor should call this before each poll() to include budget information in the trace output.

pub fn poll(&mut self, cx: &mut Context<'_>) -> Poll<Outcome<(), ()>>

Polls the stored task.

Returns Poll::Ready(Outcome) when the task is complete, or Poll::Pending if it needs to be polled again.

pub fn poll_count(&self) -> u64

Returns the number of times this task has been polled.

Trait Implementations

impl Debug for StoredTask

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

Formats the value using the given formatter.
