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

Expand description

The context of an asynchronous task.

Currently, `Context` only serves to provide access to a `&Waker` which can be used to wake the current task.

## Implementations§

### impl<'a> Context<'a>

const: unstable · source

#### pub fn from_waker(waker: &'a Waker) -> Context<'a>

Create a new `Context` from a `&Waker`.

const: unstable · source

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

Returns a reference to the `Waker` for the current task.
