Struct futures_test::task::PanicWake

pub struct PanicWake { /* fields omitted */ }

An implementation of Wake that panics when woken.

Examples

#![feature(futures_api)]
use futures_test::task::{noop_context, panic_local_waker_ref};

let mut cx = noop_context();
let cx = &mut cx.with_waker(panic_local_waker_ref());

cx.waker().wake(); // Will panic

Methods

impl PanicWake

pub fn new() -> Self

Create a new instance

Trait Implementations

impl Debug for PanicWake

fn fmt(&self, f: &mut Formatter) -> Result

Formats the value using the given formatter.

impl Default for PanicWake

fn default() -> Self

Returns the "default value" for a type.

impl Wake for PanicWake

fn wake(_arc_self: &Arc<Self>)

🔬 This is a nightly-only experimental API. (futures_api)

futures in libcore are unstable

Indicates that the associated task is ready to make progress and should be polled.

unsafe fn wake_local(arc_self: &Arc<Self>)

🔬 This is a nightly-only experimental API. (futures_api)

futures in libcore are unstable

Indicates that the associated task is ready to make progress and should be polled. This function is like wake, but can only be called from the thread on which this Wake was created.

impl UnsafeWake for PanicWake

unsafe fn clone_raw(&self) -> Waker

🔬 This is a nightly-only experimental API. (futures_api)

futures in libcore are unstable

Creates a clone of this UnsafeWake and stores it behind a Waker.

unsafe fn drop_raw(&self)

🔬 This is a nightly-only experimental API. (futures_api)

futures in libcore are unstable

Drops this instance of UnsafeWake, deallocating resources associated with it.

unsafe fn wake(&self)

🔬 This is a nightly-only experimental API. (futures_api)

futures in libcore are unstable

Indicates that the associated task is ready to make progress and should be polled.

unsafe fn wake_local(&self)

🔬 This is a nightly-only experimental API. (futures_api)

futures in libcore are unstable

Indicates that the associated task is ready to make progress and should be polled. This function is the same as wake, but can only be called from the thread that this UnsafeWake is "local" to. This allows for implementors to provide specialized wakeup behavior specific to the current thread. This function is called by LocalWaker::wake.
