Methods from __Deref<Target = AtomicBool>
pub fn load(&self, order: Ordering) -> bool
1.0.0[src]
pub fn load(&self, order: Ordering) -> bool
Loads a value from the bool.
load
takes an Ordering
argument which describes the memory ordering
of this operation.
Panics
Panics if order
is Release
or AcqRel
.
Examples
use std::sync::atomic::{AtomicBool, Ordering}; let some_bool = AtomicBool::new(true); assert_eq!(some_bool.load(Ordering::Relaxed), true);
pub fn store(&self, val: bool, order: Ordering)
1.0.0[src]
pub fn store(&self, val: bool, order: Ordering)
Stores a value into the bool.
store
takes an Ordering
argument which describes the memory ordering
of this operation.
Examples
use std::sync::atomic::{AtomicBool, Ordering}; let some_bool = AtomicBool::new(true); some_bool.store(false, Ordering::Relaxed); assert_eq!(some_bool.load(Ordering::Relaxed), false);
Panics
pub fn swap(&self, val: bool, order: Ordering) -> bool
1.0.0[src]
pub fn swap(&self, val: bool, order: Ordering) -> bool
Stores a value into the bool, returning the previous value.
swap
takes an Ordering
argument which describes the memory ordering
of this operation.
Examples
use std::sync::atomic::{AtomicBool, Ordering}; let some_bool = AtomicBool::new(true); assert_eq!(some_bool.swap(false, Ordering::Relaxed), true); assert_eq!(some_bool.load(Ordering::Relaxed), false);
pub fn compare_and_swap(
&self,
current: bool,
new: bool,
order: Ordering
) -> bool
1.0.0[src]
pub fn compare_and_swap(
&self,
current: bool,
new: bool,
order: Ordering
) -> bool
Stores a value into the bool
if the current value is the same as the current
value.
The return value is always the previous value. If it is equal to current
, then the value
was updated.
compare_and_swap
also takes an Ordering
argument which describes the memory
ordering of this operation.
Examples
use std::sync::atomic::{AtomicBool, Ordering}; let some_bool = AtomicBool::new(true); assert_eq!(some_bool.compare_and_swap(true, false, Ordering::Relaxed), true); assert_eq!(some_bool.load(Ordering::Relaxed), false); assert_eq!(some_bool.compare_and_swap(true, true, Ordering::Relaxed), false); assert_eq!(some_bool.load(Ordering::Relaxed), false);
pub fn compare_exchange(
&self,
current: bool,
new: bool,
success: Ordering,
failure: Ordering
) -> Result<bool, bool>
1.10.0[src]
pub fn compare_exchange(
&self,
current: bool,
new: bool,
success: Ordering,
failure: Ordering
) -> Result<bool, bool>
Stores a value into the bool
if the current value is the same as the current
value.
The return value is a result indicating whether the new value was written and containing
the previous value. On success this value is guaranteed to be equal to current
.
compare_exchange
takes two Ordering
arguments to describe the memory
ordering of this operation. The first describes the required ordering if the
operation succeeds while the second describes the required ordering when the
operation fails. The failure ordering can't be Release
or AcqRel
and must
be equivalent or weaker than the success ordering.
Examples
use std::sync::atomic::{AtomicBool, Ordering}; let some_bool = AtomicBool::new(true); assert_eq!(some_bool.compare_exchange(true, false, Ordering::Acquire, Ordering::Relaxed), Ok(true)); assert_eq!(some_bool.load(Ordering::Relaxed), false); assert_eq!(some_bool.compare_exchange(true, true, Ordering::SeqCst, Ordering::Acquire), Err(false)); assert_eq!(some_bool.load(Ordering::Relaxed), false);
pub fn compare_exchange_weak(
&self,
current: bool,
new: bool,
success: Ordering,
failure: Ordering
) -> Result<bool, bool>
1.10.0[src]
pub fn compare_exchange_weak(
&self,
current: bool,
new: bool,
success: Ordering,
failure: Ordering
) -> Result<bool, bool>
Stores a value into the bool
if the current 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
previous value.
compare_exchange_weak
takes two Ordering
arguments to describe the memory
ordering of this operation. The first describes the required ordering if the operation
succeeds while the second describes the required ordering when the operation fails. The
failure ordering can't be Release
or AcqRel
and must be equivalent or
weaker than the success ordering.
Examples
use std::sync::atomic::{AtomicBool, Ordering}; let val = AtomicBool::new(false); let new = true; let mut old = val.load(Ordering::Relaxed); loop { match val.compare_exchange_weak(old, new, Ordering::SeqCst, Ordering::Relaxed) { Ok(_) => break, Err(x) => old = x, } }
pub fn fetch_and(&self, val: bool, order: Ordering) -> bool
1.0.0[src]
pub fn fetch_and(&self, val: bool, order: Ordering) -> bool
Logical "and" with a boolean value.
Performs a logical "and" operation on the current value and the argument val
, and sets
the new value to the result.

1.0.0[src]
pub fn fetch_nand(&self, val: bool, order: Ordering) -> bool
Logical "nand" with a boolean value.

, and sets
the new value to the result.

use std::sync::atomic::{AtomicBool, Ordering}; let foo = AtomicBool::new(true); assert_eq!(foo.fetch_nand(false, Ordering::SeqCst), true); assert_eq!(foo.load(Ordering::SeqCst), true); let foo = AtomicBool::new(true); assert_eq!(foo.fetch_nand(true, Ordering::SeqCst), true); assert_eq!(foo.load(Ordering::SeqCst) as usize, 0); assert_eq!(foo.load(Ordering::SeqCst), false); let foo = AtomicBool::new(false); assert_eq!(foo.fetch_nand(false, Ordering::SeqCst), false); assert_eq!(foo.load(Ordering::SeqCst), true);
pub fn fetch_or(&self, val: bool, order: Ordering) -> bool
1.0.0[src]
pub fn fetch_or(&self, val: bool, order: Ordering) -> bool
Logical "or" with a boolean value.

pub fn fetch_xor(&self, val: bool, order: Ordering) -> bool
1.0.0[src]
pub fn fetch_xor(&self, val: bool, order: Ordering) -> bool
Logical "xor" with a boolean value.
Performs a logical "xor" operation on the current value and the argument val
, and sets
the new value to the result.
