Struct TaskFuture 

pub struct TaskFuture<T> { /* private fields */ }

A future adapter that executes a Task on first poll.

Execution semantics

The wrapped task runs synchronously inside the first poll call on the polling thread — this adapter does not offload work to an executor, does not yield mid-task, and never returns Poll::Pending. It exists so a synchronous task can be awaited from async code; the .await completes in one poll, blocking the async worker for the task’s full duration. Offload long-running tasks to a blocking pool instead of awaiting them directly on an async executor.

Fused

Like core::future::Ready and other std-convention one-shot futures, polling again after completion is a contract violation and panics.

Implementations

impl<T> TaskFuture<T>

where T: Task,

pub fn new(task: T, context: TaskContext) -> TaskFuture<T>

Create a new task future.

pub fn context(&self) -> &TaskContext

Get the task context.

Trait Implementations

impl<T> Future for TaskFuture<T>

where T: Task + Unpin,

fn poll( self: Pin<&mut TaskFuture<T>>, _cx: &mut Context<'_>, ) -> Poll<<TaskFuture<T> as Future>::Output>

Executes the task synchronously and returns Poll::Ready on the first call; see the type-level docs for the blocking semantics.

Panics

Panics if polled again after it has returned Poll::Ready (fused one-shot contract; a completed future has no result to hand out and no waker-based path by which Pending could ever resolve).

type Output = <T as Task>::Output

The type of value produced on completion.
