Struct AtomicRefCell 

pub struct AtomicRefCell<T: ?Sized> { /* private fields */ }

A threadsafe analogue to RefCell.

Implementations

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 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

The guard type (for example, std::sync::RwLockWriteGuard<'a, T>.)

type MutBorrowMutError<'a> = Infallible where T: 'a

The type returned in the case the value cannot be borrowed.

fn try_nonblocking_guarded_mut_borrow_mut( &mut self, ) -> Result<Self::MutGuardMut<'_>, Self::MutBorrowMutError<'_>>

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

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

This method returns an Ordering between self and other.

fn max(self, other: Self) -> Self

where Self: Sized,

Compares and returns the maximum of two values.

fn min(self, other: Self) -> Self

where Self: Sized,

Compares and returns the minimum of two values.

fn clamp(self, min: Self, max: Self) -> Self

where Self: Sized,

Restrict a value to a certain interval.

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

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

Tests for self and other values to be equal, and is used by ==.

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

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

Tests less than (for self and other) and is used by the < operator.

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

Tests greater than (for self and other) and is used by the > operator.

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

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