Struct UniqueRc 

pub struct UniqueRc<T: ?Sized>(/* private fields */);

An uniquely owned Rc.

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

Implementations

impl<T> UniqueRc<T>

pub fn new(data: T) -> Self

Available on crate feature alloc_pin_with only.

Constructs a new UniqueRc.

pub fn try_new(data: T) -> Result<Self, AllocError>

Available on crate feature alloc_try_pin_with only.

Try to constructs a new UniqueRc.

pub fn shareable(x: Self) -> Rc<T>

Convert to a shareable Rc<T>.

pub fn shareable_pin(x: Pin<Self>) -> Pin<Rc<T>>

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

pub fn new_uninit() -> UniqueRc<MaybeUninit<T>>

Constructs a new UniqueRc with uninitialized contents.

impl<T> UniqueRc<MaybeUninit<T>>

pub unsafe fn assume_init(self) -> UniqueRc<T>

Convert to an initialized Rc.

Safety

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