atomic-waker 1.1.2 is a small no_std cargo crate providing the AtomicWaker synchronization primitive (extracted from futures::task). The crate is benign with sound, minimal, and Miri-tested unsafe code gated by a well-documented two-bit atomic lock. Two low-severity quality findings concern doctests that exercise the upstream futures crate rather than this one, and a thin test suite for a concurrency primitive.
