Struct Context 

pub struct Context<'a> { /* private fields */ }

The Context of an asynchronous task.

Unlike std::task::Context, this context optionally contains a waker.

This is necessary because try_send and try_recv need to poll, but the task waker should not be saved if the try returns pending.

Implementations

impl<'a> Context<'a>

pub fn from_waker(waker: &'a Waker) -> Self

Create a new Context from a &Waker.

pub fn empty() -> Self

Create an empty context with no waker.

pub fn waker(&self) -> Option<&'a Waker>

Returns an optional reference to the Waker for the current task.

Trait Implementations

impl Debug for Context<'_>

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

Formats the value using the given formatter.

impl<'a> From<&Context<'a>> for Context<'a>

fn from(cx: &Context<'a>) -> Self

Converts to this type from the input type.

impl<'a> From<&mut Context<'a>> for Context<'a>

fn from(cx: &mut Context<'a>) -> Self

Converts to this type from the input type.

impl<'a> From<Context<'a>> for Context<'a>

fn from(cx: Context<'a>) -> Self

Converts to this type from the input type.

Layout

Note: Most layout information is completely unstable and may even differ between compilations. The only exception is types with certain repr(...) attributes. Please see the Rust Reference's “Type Layout” chapter for details on type layout guarantees.
