Atomic<T>
for RustA 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.
Add this to your Cargo.toml
:
[dependencies] atomic = "0.6"
and this to your crate root:
extern crate atomic;
