Struct CompletionWaker 

pub struct CompletionWaker<'d> { /* private fields */ }

A driver-scoped, type-erased wake target for an in-flight operation.

Unlike ReadyKey, this preserves hierarchical task wakeups. A completion can therefore wake the exact child task that registered the operation, rather than only waking the root runtime task.

Implementations

impl<'d> CompletionWaker<'d>

pub fn from_ready(driver: DriverRef<'d>, key: ReadyKey<'d>) -> Self

pub unsafe fn from_callback( target: NonNull<()>, callback: unsafe fn(NonNull<()>), ) -> Self

Safety

target must remain valid for every call to wake while this handle is live, and callback must accept that exact target.

pub fn wake(self)
