Methods from Deref<Target = Arc<Inner>>

pub fn borrow_arc<'a>(&'a self) -> ArcBorrow<'a, T>

Produce a pointer to the data that can be converted back to an Arc. This is basically an &Arc<T>, without the extra indirection. It has the benefits of an &T but also knows about the underlying refcount and can be converted into more Arc<T>s if necessary.

pub fn heap_ptr(&self) -> *const c_void

Returns the address on the heap of the Arc itself – not the T within it – for memory reporting.

If this is a static reference, this returns null.

pub fn mark_as_intentionally_leaked(&self)

Marks this Arc as intentionally leaked for the purposes of refcount logging.

It’s a logic error to call this more than once, but it’s not unsafe, as it’d just report negative leaks.

pub fn raw_ptr(&self) -> NonNull<()>

Returns a raw ptr to the underlying allocation.

pub fn is_static(&self) -> bool

Whether or not the Arc is a static reference.

pub fn is_unique(&self) -> bool

Whether or not the Arc is uniquely owned (is the refcount 1?) and not a static reference.
