[−][src]Struct core::task::RawWakerVTable
🔬 This is a nightly-only experimental API. (futures_api #50547)
futures in libcore are unstable
A virtual function pointer table (vtable) that specifies the behavior
of a RawWaker.
The pointer passed to all functions inside the vtable is the data pointer
from the enclosing RawWaker object.
The functions inside this struct are only intended be called on the data
pointer of a properly constructed RawWaker object from inside the
RawWaker implementation. Calling one of the contained functions using
any other data pointer will cause undefined behavior.
Fields
clone: unsafe fn(_: *const ()) -> RawWaker🔬 This is a nightly-only experimental API. (futures_api #50547)
futures in libcore are unstable
This function will be called when the RawWaker gets cloned, e.g. when
the Waker in which the RawWaker is stored gets cloned.
The implementation of this function must retain all resources that are
required for this additional instance of a RawWaker and associated
task. Calling wake on the resulting RawWaker should result in a wakeup
of the same task that would have been awoken by the original RawWaker.
wake: unsafe fn(_: *const ())🔬 This is a nightly-only experimental API. (futures_api #50547)
futures in libcore are unstable
This function will be called when wake is called on the Waker.
It must wake up the task associated with this RawWaker.
The implemention of this function must not consume the provided data pointer.
drop: unsafe fn(_: *const ())🔬 This is a nightly-only experimental API. (futures_api #50547)
futures in libcore are unstable
This function gets called when a RawWaker gets dropped.
The implementation of this function must make sure to release any
resources that are associated with this instance of a RawWaker and
associated task.
