Struct WakeVectorRegistration 

pub struct WakeVectorRegistration { /* private fields */ }

A registration handle for a wake vector event, returned by DriverDispatcherRef::register_wake_vector and OnDriverDispatcher::register_wake_vector. Caller must hold on to this as long as they want this wake vector to be active.

Automatically unregisters the wake vector from the dispatcher when dropped.

Implementations

impl WakeVectorRegistration

pub fn unregister(self) -> Result<(), Status>

Unregisters the wake vector. Unlike dropping the registration, this reports failures.

Returns [Status::NOT_FOUND] if the dispatcher no longer has a wake vector registered for this handle. That can happen if another registration for the same handle was unregistered with empty signals, which removes the handle’s wake vector entirely.

Trait Implementations

impl Debug for WakeVectorRegistration

fn fmt(&self, f: &mut Formatter<'_>) -> Result

Formats the value using the given formatter.

impl Drop for WakeVectorRegistration

fn drop(&mut self)

Executes the destructor for this type.

fn pin_drop(self: Pin<&mut Self>)

🔬This is a nightly-only experimental API. (pin_ergonomics)

Execute the destructor for this type, but different to Drop::drop, it requires self to be pinned.
