portable-atomic-util
Synchronization primitives built with portable-atomic.
- Provide
Arc
. (optional, requires thestd
oralloc
feature) - Provide
task::Wake
. (optional, requires thestd

feature)
See #1 for other primitives being considered for addition to this crate.

- The MSRV when this feature is enabled and the

Optional cfg
One of the ways to enable cfg is to set rustflags in the cargo config:
# .cargo/config.toml
[target.<target>]
rustflags = ["--cfg", "portable_atomic_unstable_coerce_unsized"]
Or set environment variable:
RUSTFLAGS="--cfg portable_atomic_unstable_coerce_unsized" cargo ...
-
--cfg portable_atomic_unstable_coerce_unsized
Support coercing ofArc<T>
toArc<U>
as instd::sync::Arc
.This cfg requires Rust nightly because this coercing requires unstable
CoerceUnsized
trait.See this issue comment for another known workaround.
Note: This cfg is unstable and outside of the normal semver guarantees and minor or patch versions of portable-atomic-util may make breaking changes to them at any time.
