Crate counting_pointer

counting-pointer provides structs Sc and Asc . They behave like std::rc::Rc and std::sync::Arc except for the followings.

• Sc and Asc treats only strong reference but not weak reference.
• Sc and Asc takes GlobalAlloc type as a template parameter.

It is difficult for Rc and Arc to achieve both good performance and small memory usage at the same time. This crate gives up supporting weak reference to do it.

Structs

Asc	A thread-safe strong reference-counting pointer. 'Asc' stands for 'Atomic Strong Counted.'
Sc	A single-threaded strong reference-counting pointer. 'Sc' stands for 'Strong Counted.'
