Comparison: the Swift folks have spent a while hammering out what they think the relevant traits/protocols are, though the final form is only just now going to be released in Swift 6.0:

## Introduction
This proposal adds a limited set of low-level atomic operations to the Standard Library, including native spellings for C++-style memory orderings. Our goal is to enable intrepid library authors and developers writing system level code to start building synchronization constructs directly in Swift.
