Struct atomic_refcell::AtomicRefCell

pub struct AtomicRefCell<T: ?Sized> {
    borrow: AtomicUsize,
    value: UnsafeCell<T>,
}

A threadsafe analogue to RefCell.

Fields

borrow: AtomicUsize

value: UnsafeCell<T>

Methods

impl<T> AtomicRefCell<T>

pub fn new(value: T) -> AtomicRefCell<T>

Creates a new AtomicRefCell containing value.

pub fn into_inner(self) -> T

Consumes the AtomicRefCell, returning the wrapped value.

impl<T: ?Sized> AtomicRefCell<T>

pub fn borrow(&self) -> AtomicRef<T>

Immutably borrows the wrapped value.

pub fn borrow_mut(&self) -> AtomicRefMut<T>

Mutably borrows the wrapped value.

pub fn as_ptr(&self) -> *mut T

Returns a raw pointer to the underlying data in this cell.

External synchronization is needed to avoid data races when dereferencing the pointer.
