Expand description
A maybe-atomic shared mutable fundamental type T
.
This trait is implemented by both the atomic wrapper type for T
, and by
Cell<T>
, providing a consistent interface for interacting with the two
types.
This trait provides methods predicated on marker traits for the underlying
fundamental. Only types which can be viewed as sequences of bits may use the
functions for bit-wise arithmetic, and only types which can be used as
integers may use the functions for numeric arithmetic. Use of these methods
on insufficient underlying types (for example, Radium::fetch_and
on an
atomic or cell-wrapped pointer) will cause a compiler error.
Associated Types
Required methods
Returns a mutable reference to the underlying value.
This is safe because the mutable reference to self
guarantees that no
other references exist to this value.
fn into_inner(self) -> Self::Item
fn into_inner(self) -> Self::Item
Consumes the wrapper and returns the contained value.
This is safe as passing by value ensures no other references exist.
Load a value from this object.
Ordering values are ignored by non-atomic types.
See also: AtomicUsize::load
.
Store a value in this object.
Ordering arguments are ignored by non-atomic types.
See also: AtomicUsize::store
.
Swap with the value stored in this object.
Ordering arguments are ignored by non-atomic types.
See also: AtomicUsize::swap
.
Stores a value into this object if the currently-stored value is the
same as the current
value.
The return value is always the previously-stored value. If it is equal to
current
, then the value was updated with new
.
Ordering arguments are ignored by non-atomic types.
See also: AtomicUsize::compare_and_swap
.
Stores a value into this object if the currently-stored value is the
same as the current
value.
The return value is a Result
indicating whether the new value was
written, and containing the previously-stored value. On success, this
value is guaranteed to be equal to current
.
Ordering arguments are ignored by non-atomic types.
See also: AtomicUsize::compare_exchange
.
Stores a value into this object if the currently-stored value is the
same as the current
value.
Unlike compare_exchange
, this function is allowed to spuriously fail
even when the comparison succeeds, which can result in more efficient
code on some platforms. The return value is a Result
indicating
whether the new value was written, and containing the previously-stored
value.
Ordering arguments are ignored by non-atomic types.
See also: AtomicUsize::compare_exchange_weak
.
Performs a bitwise “and” on the currently-stored value and the argument
value
, and stores the result in self
.
Returns the previously-stored value.
Ordering arguments are ignored by non-atomic types.
See also: AtomicUsize::fetch_and
.
Performs a bitwise “nand” on the currently-stored value and the argument
value
, and stores the result in self
.
Returns the previously-stored value.
Ordering arguments are ignored by non-atomic types.
See also: AtomicUsize::fetch_nand
.
Performs a bitwise “or” on the currently-stored value and the argument
value
, and stores the result in self
.
Returns the previously-stored value.
Ordering arguments are ignored by non-atomic types.
See also: AtomicUsize::fetch_or
.
Performs a bitwise “xor” on the currently-stored value and the argument
value
, and stores the result in self
.
Returns the previously-stored value.
Ordering arguments are ignored by non-atomic types.
See also: AtomicUsize::fetch_xor
.
Adds value
to the currently-stored value, wrapping on overflow, and
stores the result in self
.
Returns the previously-stored value.
Ordering arguments are ignored by non-atomic types.
See also: AtomicUsize::fetch_add
.
Subtracts value
from the currently-stored value, wrapping on
underflow, and stores the result in self
.
Returns the previously-stored value.
Ordering arguments are ignored by non-atomic types.
