deps: Prefer portable_atomic over native AtomicU64#3994
Merged
Conversation
On some 32 bit platforms there is no AtomicU64. Portable_atomic uses the underlying atomic on 64 bit platforms, so there is no perf overhead on those. We already have portable_atomic in the deps,

Description
On some 32 bit platforms there is no AtomicU64. Portable_atomic uses the underlying atomic on 64 bit platforms, so there is no perf overhead on those.
We already have portable_atomic in the deps, from moka and once_cell. So there is no additional dependency cost.
This is needed to get iroh to work on 32 bit platforms without native support for AtomicU64.
