[−][src]Struct lockfreehashmap::atomic::AtomicPtr
Wrapper around [Atomic]. Represents a pointer that can be null at first but never again afterwards.
Methods
impl<T> AtomicPtr<T>[src]
impl<T> AtomicPtr<T>pub fn new(value: Option<T>) -> Self[src]
pub fn new(value: Option<T>) -> Selfpub fn load<'g>(&self, guard: &'g Guard) -> MaybeNull<'g, T>[src]
pub fn load<'g>(&self, guard: &'g Guard) -> MaybeNull<'g, T>pub fn relaxed_exists<'g>(&self, guard: &'g Guard) -> bool[src]
pub fn relaxed_exists<'g>(&self, guard: &'g Guard) -> boolCheck if the pointer is not null (i.e. the value exists), using Ordering::Relaxed.
pub unsafe fn take<'g>(&self, guard: &'g Guard) -> Option<Box<T>>[src]
pub unsafe fn take<'g>(&self, guard: &'g Guard) -> Option<Box<T>>Swaps out the current value, leaving null in its place. Equivalent to [Option::take()].
Unsafe
This is unsafe because there must be no other pointers that can ever access this
AtomicPtr after this function is called. This is intended to be used for [Drop::drop()].
