Struct pin_init::UniqueArc[−][src]

#[repr(transparent)]
pub struct UniqueArc<T: ?Sized>(_);
This is supported on crate feature alloc only.
Expand description

An uniquely owned Arc.

Useful for constructing Arc, since we are certain that when Arc is initially created, there is an unique reference. Once initially mutation is done, it can be convert to Arc with shareable().

Implementations

impl<T> UniqueArc<T>[src]

pub fn new(data: T) -> Self[src]

Constructs a new UniqueArc.

pub fn shareable(x: Self) -> Arc<T>[src]

Convert to a shareable Arc<T>.

pub fn shareable_pin(x: Pin<Self>) -> Pin<Arc<T>>[src]

Convert to a shareable Pin<Arc<T>>.

pub fn new_uninit() -> UniqueArc<MaybeUninit<T>>[src]

Constructs a new UniqueArc with uninitialized contents.

impl<T> UniqueArc<MaybeUninit<T>>[src]

pub unsafe fn assume_init(self) -> UniqueArc<T>[src]

Convert to an initialized Arc.

Safety

This function is unsafe as this is equivalent to MaybeUninit::assume_init.

Trait Implementations

impl<T> Deref for UniqueArc<T>[src]

type Target = T

The resulting type after dereferencing.

fn deref(&self) -> &T[src]

Dereferences the value.

impl<T> DerefMut for UniqueArc<T>[src]

fn deref_mut(&mut self) -> &mut T[src]

Mutably dereferences the value.
