atomic 0.6.0

Generic Atomic<T> wrapper type
Generic `Atomic<T>` for Rust

[![Build Status](]( [![](](

A Rust library which provides a generic `Atomic<T>` type for all `T: NoUninit` types, unlike the standard library which only provides a few fixed atomic types (`AtomicBool`, `AtomicIsize`, `AtomicUsize`, `AtomicPtr`). The `NoUninit` bound is from the [bytemuck] crate, and indicates that a type has no internal padding bytes. You will need to derive or implement this trait for all types used with `Atomic<T>`.

This library will use native atomic instructions if possible, and will otherwise fall back to a lock-based mechanism. You can use the `Atomic::<T>::is_lock_free()` function to check whether native atomic operations are supported for a given type. Note that a type must have a power-of-2 size and alignment in order to be used by native atomic instructions.

This crate uses `#![no_std]` and only depends on libcore.
