[−][src]Struct atomic_take::AtomicTake
A container with an atomic take operation.
Methods
impl<T> AtomicTake<T>
[src]
pub fn new(value: T) -> Self
[src]
Create a new AtomicTake
with the given value.
pub fn empty() -> Self
[src]
Create an empty AtomicTake
that contains no value.
pub fn take(&self) -> Option<T>
[src]
Takes out the value from this AtomicTake
. It is guaranteed that exactly one
caller will receive the value and all others will receive None
.
pub fn take_mut(&mut self) -> Option<T>
[src]
This methods does the same as take
, but does not use an atomic swap.
This is safe because you cannot call this method without unique access to the
AtomicTake
, so no other threads will try to take it concurrently.
pub fn is_taken(&self) -> bool
[src]
Check whether the value is taken. Note that if this returns false
, then this
is immediately stale if another thread could be concurrently trying to take it.
pub fn insert(&mut self, value: T) -> Option<T>
[src]
Insert a new value into the AtomicTake
and return the previous value.
This function requires unique access to ensure no other threads accesses the
AtomicTake
concurrently, as this operation cannot be performed atomically
without a lock.
