Struct Blocking 

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

The future spawn_blocking returns: the job’s value once a pool thread has run it.

Dropping it before the job starts cancels the job, which then never runs. Dropping it while the job runs lets the job finish on its thread and discards the value: a blocking call has no way to be interrupted. Blocking::detach keeps the job without the value. Awaitable from any executor, day::task included.

Implementations

impl<T> Blocking<T>

pub fn detach(self)

Let the job run to completion without waiting for its value: for work whose effect is its own completion callback. A pooled job keeps its queue slot; an inline one runs now.

Trait Implementations

impl<T> Drop for Blocking<T>

Available on non-WebAssembly only.

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.

impl<T> Future for Blocking<T>

type Output = Result<T, BlockingError>

The type of value produced on completion.

fn poll(self: Pin<&mut Self>, cx: &mut Context<'_>) -> Poll<Self::Output>

Attempts to resolve the future to a final value, registering the current task for wakeup if the value is not yet available.
