atomic-primitive

Traits for primitive atomic types in Rust.

These traits provide a simple hierarchy for generic programming with Rust's primitive atomic types:

• PrimitiveAtomic: AtomicBool and all atomic integer types;
  • PrimitiveAtomicInteger: all atomic integer types;
    • PrimitiveAtomicSigned: AtomicI8, AtomicI16, AtomicI32, AtomicI64, AtomicIsize;
    • PrimitiveAtomicUnsigned: AtomicU8, AtomicU16, AtomicU32, AtomicU64, AtomicUsize.

Additionally, AtomicPrimitive maps non-atomic primitive types to their atomic counterparts, mirroring the unstable core::sync::atomic::AtomicPrimitive trait.

It is not a goal of this crate to add any functionality to the atomic types, only to expose what is already available in the standard library in a more generic way, and make a few experimental traits and types available on stable. The only addition is an AtomicPrimitive bound on PrimitiveAtomic::Value, which enables bidirectional navigation between atomic and non-atomic types. The traits are also sealed against downstream implementations to allow expansion in a non-breaking way.

Compatibility

This crate is currently tested for Rust 1.85 and greater.
