compact-rc

Low-memory reference-counting pointers.

The types in this crate have almost the same methods as standard Rc and Arc. The differences from the standard type are as follows:

• Weak reference is not supported.
• Small integers can be used as refcount.

| Crate | Strong count | Weak count | | ------------ | ---------------------------------- | ------------- | | std | usize | usize | | compact-rc | u8, u16, u32, u64, usize | not supported |

Example

```rust use compact_rc::Rc8;

fn main() { // rc1 is a pointer containing i8 value with u8 refcount. let rc1: Rc8 = Rc8::new(100);

assert_eq!(Rc8::strong_count(&rc1), 1);
assert_eq!(*rc1, 100);

// Increment the refcount.
// The value is shared by rc1 and rc2.
let rc2 = rc1.clone();

assert_eq!(Rc8::strong_count(&rc1), 2);
assert_eq!(Rc8::strong_count(&rc2), 2);
assert_eq!(*rc1, 100);
assert_eq!(*rc2, 100);
assert!(Rc8::ptr_eq(&rc1, &rc2));

} ```
