Crate readme

Short description Portable atomic types including support for 128-bit atomics, atomic float, etc.

Long description This crate provides various atomic integer types (Atomic{I,U}{8,16,32,64}) for all targets that support atomic CAS, including AtomicI128, AtomicU128, AtomicF32, and AtomicF64. It allows for atomic load/store operations even on targets without standard library support for atomics. Features include compiler support for Rust 1.34+, optional features for atomic floats, and compatibility for no_std environments. The crate offers mechanisms to deal with multi-core systems and provides custom error messages for unsupported targets.

Features • AtomicI128 and AtomicU128 support • AtomicF32 and AtomicF64 support • AtomicF16 and AtomicF128 support for unstable floats • Support for no_std environments • Compiler detection for 128-bit atomics on certain architectures
