atomic-traits

The traits for generic atomic operations in Rust.

Compatibility

The crate is tested for rustc 1.8 and greater.

Usage

Add this to your Cargo.toml:

toml [dependencies] atomic-traits = "0.1"

and this to your crate root:

rust extern crate atomic_traits;

Example

```rust use std::sync::atomic::{AtomicUsize, Ordering};

use numtraits::One; use atomictraits::{Atomic, NumOps, fetch};

[derive(Debug, Default)]

pub struct RefCnt(T);

impl RefCnt where T: Atomic + NumOps + Default, ::Type: One { pub fn inc(&self) -> ::Type { self.0.fetch_add(::Type::one(), Ordering::Acquire) }

pub fn dec(&self) -> <T as Atomic>::Type {
    self.0.fetch_sub(<T as Atomic>::Type::one(), Ordering::Release)
}

pub fn val(&self) -> <T as Atomic>::Type {
    self.0.load(Ordering::SeqCst)
}

}

let refcnt = RefCnt::::default();

asserteq!(refcnt.inc(), 0); asserteq!(refcnt.dec(), 1); assert_eq!(refcnt.val(), 0); ```
