Implementations

impl EventHandles

pub const fn dummy() -> EventHandles

Empty collection.

pub fn is_dummy(&self) -> bool

Returns true if empty or all handles are dummy.

pub fn perm(self)

Drop all handles without stopping their behavior.

pub fn push(&mut self, other: EventHandle) -> &mut EventHandles

Add other handle to the collection.

pub fn clear(&mut self)

Drop all handles.
