Struct Task 

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

the handle of a spawned task; dropping it cancels the task (detach keeps it running)

Implementations

impl<T> Task<T>

pub fn is_done(&self) -> bool

finished, cancelled or dropped by its executor (the future is gone or goes with the executor’s next run)

pub fn is_cancelled(&self) -> bool

it ended without a value: cancel() came first, or its executor went away

pub fn take(&self) -> Option<T>

the result, once (None: still running, cancelled or already taken)

pub fn cancel(&self)

stop the task: its future is dropped at the executor’s next run (a finished task keeps its result)

pub fn detach(self)

let the task run on without a handle

Trait Implementations

impl<T> Drop for Task<T>

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 Task<T>

type Output = Result<T, Cancelled>

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.
