Struct EventHandle 

Source 
pub struct EventHandle<O: OwnerMut<Event>>(/* private fields */);
Expand description

Represents a handle into the listing of the current task in an Event. When this handle is dropped, that task is removed from the event’s set.

Implementations§

Source§

impl<O: OwnerMut<Event>> EventHandle<O>

Source

pub fn is_done(&self) -> bool

Returns true if the event handle is orphaned, i.e. the parent event object no longer exists.

Source

pub fn clear(&mut self)

Nullifies the handle. This has the same effect as dropping it or destroying the parent event object.
