# 1.36.0[−][src]Struct std::task::Context

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

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.

## Methods

### `impl<'a> Context<'a>`[src]

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

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

#### `pub fn waker(&self) -> &'a Waker`[src]

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