Trait for refcount

Required Associated Types

type Value

Type of count

Required Methods

fn one() -> Self

Creates a new RefCount object.

The object is initialized as “one”.

fn is_one(val: &Self::Value) -> bool

Checks a value equals to one.

fn load(&self) -> Self::Value

Gets a current value.

fn fetch_inc(&self) -> Self::Value

Increments its value and returns previous value.

fn fetch_dec(&self) -> Self::Value

Decrements its value and returns previous value.
