This PR enables an option in
futures-core
that replaces the atomic usage inAtomicWaker
withportable-atomic
, and also exposes that flag infutures-util
. This intends to make it sofutures-core
can be used on platforms without atomics, like AVR.I look through
futures-util
and didn't see any other usage of atomics that wasn't also locked behind allocation, so I think this is the best I can do here.
