[−][src]Struct futures::task::Context
🔬 This is a nightly-only experimental API. (futures_api
)
futures in libcore are unstable
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

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

Returns a reference to the Waker
for the current task.
