Abstraction of IOCP operations.
Required Methods§
sourceunsafe fn operate(
self: Pin<&mut Self>,
optr: *mut OVERLAPPED,
) -> Poll<Result<usize>>
unsafe fn operate( self: Pin<&mut Self>, optr: *mut OVERLAPPED, ) -> Poll<Result<usize>>
Perform Windows API call with given pointer to overlapped struct.
It is always safe to cast optr to a pointer to
Overlapped<Self>.
§Safety
selfmust be alive until the operation completes.- Should not use [
Overlapped::op].
