[][src]Struct crossbeam_utils::atomic::AtomicCell

pub struct AtomicCell<T> { /* fields omitted */ }

A thread-safe mutable memory location.

This type is equivalent to Cell, except it can also be shared among multiple threads.

Operations on AtomicCells use atomic instructions whenever possible, and synchronize using global locks otherwise. You can call AtomicCell::<T>::is_lock_free() to check whether atomic instructions or locks will be used.

Methods

impl<T> AtomicCell<T>
[src]

pub fn new(val: T) -> AtomicCell<T>
[src]

Creates a new atomic cell initialized with val.

Examples

use crossbeam_utils::atomic::AtomicCell;

let a = AtomicCell::new(7);

Important traits for &'a mut W
pub fn get_mut(&mut self) -> &mut T
[src]

Returns a mutable reference to the inner value.

Examples

use crossbeam_utils::atomic::AtomicCell;

let mut a = AtomicCell::new(7);
*a.get_mut() += 1;

assert_eq!(a.load(), 8);

pub fn into_inner(self) -> T
[src]

Unwraps the atomic cell and returns its inner value.

Examples

use crossbeam_utils::atomic::AtomicCell;

let mut a = AtomicCell::new(7);
let v = a.into_inner();

assert_eq!(v, 7);

pub fn is_lock_free() -> bool
[src]

Returns true if operations on values of this type are lock-free.

If the compiler or the platform doesn't support the necessary atomic instructions, AtomicCell<T> will use global locks for every potentially concurrent atomic operation.

Examples

use crossbeam_utils::atomic::AtomicCell;

// This type is internally represented as `AtomicUsize` so we can just use atomic
// operations provided by it.
assert_eq!(AtomicCell::<usize>::is_lock_free(), true);

// A wrapper struct around `isize`.
struct Foo {
    bar: isize,
}
// `AtomicCell<Foo>` will be internally represented as `AtomicIsize`.
assert_eq!(AtomicCell::<Foo>::is_lock_free(), true);

// Operations on zero-sized types are always lock-free.
assert_eq!(AtomicCell::<()>::is_lock_free(), true);

// Very large types cannot be represented as any of the standard atomic types, so atomic
// operations on them will have to use global locks for synchronization.
assert_eq!(AtomicCell::<[u8; 1000]>::is_lock_free(), false);

pub fn store(&self, val: T)
[src]

Stores val into the atomic cell.

Examples

use crossbeam_utils::atomic::AtomicCell;

let a = AtomicCell::new(7);

assert_eq!(a.load(), 7);
a.store(8);
assert_eq!(a.load(), 8);

pub fn swap(&self, val: T) -> T
[src]

Stores val into the atomic cell and returns the previous value.

Examples

use crossbeam_utils::atomic::AtomicCell;

let a = AtomicCell::new(7);

assert_eq!(a.load(), 7);
assert_eq!(a.swap(8), 7);
assert_eq!(a.load(), 8);

impl<T: Copy> AtomicCell<T>
[src]

pub fn load(&self) -> T
[src]

Loads a value.

Examples

use crossbeam_utils::atomic::AtomicCell;

let a = AtomicCell::new(7);

assert_eq!(a.load(), 7);

impl<T: Copy + Eq> AtomicCell<T>
[src]

pub fn compare_and_swap(&self, current: T, new: T) -> T
[src]

If the current value equals current, stores new into the atomic cell.

The return value is always the previous value. If it is equal to current, then the value was updated.

Examples

use crossbeam_utils::atomic::AtomicCell;

let a = AtomicCell::new(1);

assert_eq!(a.compare_exchange(2, 3), Err(1));
assert_eq!(a.load(), 1);

assert_eq!(a.compare_exchange(1, 2), Ok(1));
assert_eq!(a.load(), 2);

pub fn compare_exchange(&self, current: T, new: T) -> Result<T, T>
[src]

If the current value equals current, stores new into the atomic cell.

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.

Examples

use crossbeam_utils::atomic::AtomicCell;

let a = AtomicCell::new(1);

assert_eq!(a.compare_exchange(2, 3), Err(1));
assert_eq!(a.load(), 1);

assert_eq!(a.compare_exchange(1, 2), Ok(1));
assert_eq!(a.load(), 2);
