[−][src]Struct lockfreehashmap::atomic::MaybeNull
Similarly to [NotNull], this is a wrapper around [Shared] for values where the pointer could be null.
Methods
impl<'t, T> MaybeNull<'t, T>[src]
impl<'t, T> MaybeNull<'t, T>pub fn as_option(&self) -> Option<NotNull<'t, T>>[src]
pub fn as_option(&self) -> Option<NotNull<'t, T>>pub unsafe fn try_defer_drop(self, guard: &Guard)[src]
pub unsafe fn try_defer_drop(self, guard: &Guard)Drop the underlying value behind this pointer if it's not null and after enough epochs have passed.
Unsafe
This is unsafe because only one thread can call this for any single underlying value.
