Struct WaitCanceler 

pub struct WaitCanceler { /* private fields */ }

Return values for wait_async methods.

Calling cancel will cancel any running wait.

Does not implement Clone or Copy so that only a single canceler exists per wait.

Implementations

impl WaitCanceler

pub fn new_noop() -> Self

pub fn new_zxio(zxio: ZxioWeak, inner: PortWaitCanceler) -> Self

pub fn new_port(inner: PortWaitCanceler) -> Self

pub fn merge(self, other: Self) -> Self

Equivalent to merge_unbounded, except that it enforces that the resulting vector of cancellers is small enough to avoid being separately allocated on the heap.

If possible, use this function instead of merge_unbounded, because it gives us better tools to keep this code path optimized.

pub fn merge_unbounded(_: Self, _: Self) -> Self

Creates a new WaitCanceler that is equivalent to canceling both its arguments.

pub fn cancel(self)

Cancel the pending wait.

Takes self by value since a wait can only be canceled once.
