Implementations

impl VarHandles

pub const fn dummy() -> Self

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: VarHandle) -> &mut Self

Add the other handle to the collection, if it is not dummy.

pub fn clear(&mut self)

Drop all handles.
