Struct layout_2020::cell::ArcRefCell

pub(crate) struct ArcRefCell<T> {
    value: Arc<AtomicRefCell<T>>,
}

Fields

value: Arc<AtomicRefCell<T>>

Implementations

impl<T> ArcRefCell<T>

pub fn new(value: T) -> Self

Methods from Deref<Target = 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.

Trait Implementations

impl<T> Clone for ArcRefCell<T>

fn clone(&self) -> Self

Returns a copy of the value.

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

Performs copy-assignment from source.

impl<T> Debug for ArcRefCell<T>

where T: Debug,

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

Formats the value using the given formatter.

impl<T> Default for ArcRefCell<T>

where T: Default,

fn default() -> Self

Returns the “default value” for a type.

impl<T> Deref for ArcRefCell<T>

type Target = AtomicRefCell<T>

where S: Serializer,

Serialize this value into the given Serde serializer.
