Struct atomic_refcell::AtomicRefCell

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

A threadsafe analogue to RefCell.

Fields

borrow: AtomicUsize

value: UnsafeCell<T>

Implementations

impl<T> AtomicRefCell<T>

pub const 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 try_borrow(&self) -> Result<AtomicRef<'_, T>, BorrowError>

Attempts to immutably borrow the wrapped value, but instead of panicking on a failed borrow, returns Err.

pub fn borrow_mut(&self) -> AtomicRefMut<'_, T>

Mutably borrows the wrapped value.

pub fn try_borrow_mut(&self) -> Result<AtomicRefMut<'_, T>, BorrowMutError>

Attempts to mutably borrow the wrapped value, but instead of panicking on a failed borrow, returns Err.

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.

pub fn get_mut(&mut self) -> &mut T

Returns a mutable reference to the wrapped value.

No runtime checks take place (unless debug assertions are enabled) because this call borrows AtomicRefCell mutably at compile-time.

Trait Implementations

impl<T: Clone> Clone for AtomicRefCell<T>

fn clone(&self) -> AtomicRefCell<T>

Returns a copy of the value.

fn clone_from(&mut self, source: &Self)

Performs copy-assignment from source.

impl<T: ?Sized + Debug> Debug for AtomicRefCell<T>

fn fmt(&self, f: &mut Formatter<'_>) -> Result

Formats the value using the given formatter.

impl<T: Default> Default for AtomicRefCell<T>

fn default() -> AtomicRefCell<T>

Returns the “default value” for a type.

impl<T> From<T> for AtomicRefCell<T>

fn from(t: T) -> AtomicRefCell<T>

Converts to this type from the input type.

impl<T: ?Sized + Ord> Ord for AtomicRefCell<T>

fn cmp(&self, other: &AtomicRefCell<T>) -> Ordering

This method returns an Ordering between self and other.

impl<T: ?Sized + PartialEq> PartialEq for AtomicRefCell<T>

fn eq(&self, other: &AtomicRefCell<T>) -> bool

This method tests for self and other values to be equal, and is used by ==.

fn ne(&self, other: &Rhs) -> bool

This method tests for !=. The default implementation is almost always sufficient, and should not be overridden without very good reason.

impl<T: ?Sized + PartialOrd> PartialOrd for AtomicRefCell<T>

fn partial_cmp(&self, other: &AtomicRefCell<T>) -> Option<Ordering>

This method returns an ordering between self and other values if one exists.

fn lt(&self, other: &Rhs) -> bool

This method tests less than (for self and other) and is used by the < operator.

fn le(&self, other: &Rhs) -> bool

This method tests less than or equal to (for self and other) and is used by the <= operator.

fn gt(&self, other: &Rhs) -> bool

This method tests greater than (for self and other) and is used by the > operator.

fn ge(&self, other: &Rhs) -> bool

This method tests greater than or equal to (for self and other) and is used by the >= operator.
