This crate polyfills atomics on targets where they're not available, using critical sections. It is intended to be a drop-in replacement for
There are two "levels" of polyfilling:
- Native: No polyfilling is performed, the native
- Full: Both load/store and compare-and-set operations are polyfilled.
Polyfilling requires a
critical-section implementation for the current target. Check the
critical-section README for details.
The right polyfill level is automatically picked based on the target and the atomic width:
|Target||Level||Level for u64/i64|
For targets not listed above,
atomic-polyfill assumes nothing and reexports
core::sync::atomic::*. No polyfilling is done. PRs for polyfilling more targets are welcome :)
