pub struct MockTask { /* fields omitted */ }

Mock task

A mock task is able to intercept and track wake notifications.

Methods

impl MockTask

pub fn new() -> Self

Create a new mock task

pub fn poll<T, F>(&mut self, fut: T) -> Poll<F::Output> where
    T: AsPinMut<F>,
    F: Future, 

Poll a future

pub fn enter<F, R>(&mut self, f: F) -> R where
    F: FnOnce(&mut Context) -> R, 

Run a closure from the context of the task.

Any wake notifications resulting from the execution of the closure are tracked.

pub fn is_woken(&self) -> bool

Returns true if the inner future has received a wake notification since the last call to enter.

pub fn waker_ref_count(&self) -> usize

Returns the number of references to the task waker

The task itself holds a reference. The return value will never be zero.
