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.
