Internal reference counting support.
Many C types already have their own reference counting mechanism (e.g. by storing a
refcount_t). This module provides support for directly using their internal reference count
from Rust; instead of making users have to use an additional Rust-reference count in the form of
Arc.
The smart pointer ARef<T> acts similarly to Arc<T> in that it holds a refcount on the
underlying object, but this refcount is internal to the object. It essentially is a Rust
implementation of the get_ and put_ pattern used in C for reference counting.
To make use of ARef<MyType>, MyType needs to implement AlwaysRefCounted. It is a trait
for accessing the internal reference count of an object of the MyType type.
Structs§
- ARef
- An owned reference to an always-reference-counted object.
Traits§
- AlwaysRefCounted 
- Types that are always reference counted.
