Struct Strong 

pub struct Strong<T: RefCnt + ?Sized>(NonNull<T>);

Strong reference to reference-counted memory block.

The main different from alloc::sync::Arc is this type store the number of references alongside the data.

Tuple Fields

0: NonNull<T>

Implementations

impl<T: RefCnt + ?Sized> Strong<T>

pub unsafe fn new(v: *const T) -> Self

Safety

v cannot be null and must point to initialized value.

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

Trait Implementations

impl<T: RefCnt + ?Sized> Clone for Strong<T>

fn clone(&self) -> Self

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl<T: RefCnt + ?Sized> Deref for Strong<T>

type Target = T

The resulting type after dereferencing.

fn deref(&self) -> &Self::Target

Dereferences the value.

impl<T: RefCnt + ?Sized> Drop for Strong<T>

fn drop(&mut self)

Executes the destructor for this type.

fn pin_drop(self: Pin<&mut Self>)

🔬This is a nightly-only experimental API. (pin_ergonomics)

Execute the destructor for this type, but different to Drop::drop, it requires self to be pinned.

impl<T: RefCnt + Send + ?Sized> Send for Strong<T>

impl<T: RefCnt + Sync + ?Sized> Sync for Strong<T>
