 This package implements an atomics library for Swift, providing atomic operations for a variety of Swift types, including integers and pointer values. The goal is to enable intrepid developers to start building synchronization constructs directly in Swift.

 - it enables custom storage representations (such as the one used by atomic strong references), and

 While the underlying pointer-based atomic operations are exposed as static methods on the corresponding [`AtomicStorage`][AtomicStorage] types, we strongly recommend the use of higher-level atomic wrappers to manage the details of preparing/disposing atomic storage. This version of the library provides two wrapper types:
