Trait for type constructors of reference-counting pointers.

Safety

T may be !Unpin, and SharedPointer may be held in a pinned form (Pin<SharedPointer<T, Self>>). As such, the implementation of this trait must uphold the pinning invariants for T while it’s held in Self. Specifically, this necessitates the following:

• &mut T is only exposed through the trait methods returning &mut T.

• The implementor must not move out the contained T unless the semantics of trait methods demands that.

• Self::drop drops T in place.

Required Methods

fn new<T>(v: T) -> Self

fn from_box<T>(v: Box<T>) -> Self

unsafe fn as_ptr<T>(&self) -> *const T

unsafe fn deref<T>(&self) -> &T

unsafe fn try_unwrap<T>(self) -> Result<T, Self>

unsafe fn get_mut<T>(&mut self) -> Option<&mut T>

unsafe fn make_mut<T>(&mut self) -> &mut T

where T: Clone,

unsafe fn strong_count<T>(&self) -> usize

unsafe fn clone<T>(&self) -> Self

unsafe fn drop<T>(&mut self)

Dyn Compatibility

This trait is not dyn compatible.

In older versions of Rust, dyn compatibility was called "object safety", so this trait is not object safe.
