[−][src]Struct futures::task::RawWaker
🔬 This is a nightly-only experimental API. (futures_api)
futures in libcore are unstable
A RawWaker allows the implementor of a task executor to create a Waker
which provides customized wakeup behavior.
It consists of a data pointer and a virtual function pointer table (vtable) that
customizes the behavior of the RawWaker.
Methods
impl RawWaker[src]
pub const fn new(data: *const (), vtable: &'static RawWakerVTable) -> RawWaker[src]
🔬 This is a nightly-only experimental API. (futures_api)

Creates a new RawWaker from the provided data pointer and vtable.
The data pointer can be used to store arbitrary data as required
by the executor. This could be e.g. a type-erased pointer to an Arc
that is associated with the task.
The value of this poiner will get passed to all functions that are part
of the vtable as the first parameter.
The vtable customizes the behavior of a Waker which gets created
from a RawWaker. For each operation on the Waker, the associated
function in the vtable of the underlying RawWaker will be called.
