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.
