impl<T: ?Sized> ArcBox<T>

pub unsafe fn from_raw(ptr: *const T) -> Self

Construct an ArcBox from a raw pointer.

Safety

The raw pointer must have previously been acquired by a call to ArcBox::into_raw, or Arc::into_raw where the Arc is known unique.

pub fn get_mut(this: &mut Self) -> Option<&mut T>

Deprecated:

Use DerefMut instead

Get a mutable reference into the ArcBox.

This method exists only for API compatibility with Arc. Use DerefMut instead.

pub fn get_mut_unchecked(this: &mut Self) -> &mut T

Deprecated:

Use DerefMut instead

Get a mutable reference into the ArcBox.

This method exists only for API compatibility with Arc. Use DerefMut instead.

pub fn as_raw(this: &Self) -> NonNull<T>

Returns a raw pointer to the object T pointed to by this ArcBox.

Note that this returns a ptr::NonNull, not a raw pointer. That makes this function equivalent to as_raw_non_null.

pub fn into_raw(this: Self) -> NonNull<T>

Consume the ArcBox, returning the wrapped pointer.

To avoid a memory leak, the pointer must be converted back to a ArcBox, using ArcBox::from_raw, or directly into a Arc, using Arc::from_raw.

Note that this returns a ptr::NonNull, not a raw pointer. That makes this function equivalent to into_raw_non_null.

pub fn leak<'a>(this: Self) -> &'a mut T where
    T: 'a, 

Consume and leak the ArcBox.

pub fn new(data: T) -> Self where
    T: Sized, 

Create a new ArcBox.

pub fn pin(x: T) -> Pin<ArcBox<T>> where
    T: Sized, 

Construct a new Pin<ArcBox<T>>. If T does not implement Unpin, then the data will be pinned in memory and unable to be moved.

pub fn into_inner(this: Self) -> T where
    T: Sized, 

Deconstruct this ArcBox, returning the inner value.
