Helper traits for working with maybe-atomic values

radium

Latest Version Documentation

radium provides a helper trait with a uniform API for interacting with both atomic types like AtomicUsize, and non-atomic types like Cell<usize>.

This crate is #![no_std]-compatible, and uses no non-core types.

For more details, see the trait's documentation.

Additionally, the radium::types module provides a set of type aliases for all of the atomic primitive types (bool, signed and unsigned integers up to 64, *mut T) that map to the atomic type when it is present, and the Cell wrapper when it is not. This allows you to have stable, portable, type names that do not require cfg guards to remove them for targets that do not support them.

Target Architecture Compatibility

Not all Rust targets have symbols for atomic types! The compiler knows what targets have what atomics, but does not yet expose this information on the stable channel for libraries to use.

As such, radium uses a build script to detect the target architecture and emit our own directives that mark the presence or absence of an atomic integer.

If radium does not work for your architecture, please update the build script to handle your target string and submit a pull request.

Feelin' lazy: Has someone already written a helper trait abstracting operations over AtomicUsize and Cell<usize> for generic code which may not care about atomicity?

no but call the crate radium

(since people didn't care that it was radioactive and used it in everything)
