Add OnceCell::with_value to create initialized OnceCell in const context.
Improve Clone implementation for OnceCell.
Rewrite parking_lot version on top of parking_lot_core, for even smaller cells!
1.10
upgrade parking_lot to 0.12.0 (note that this bumps MSRV with parking_lot feature enabled to 1.49.0).
1.9
Added an atomic-polyfill optional dependency to compile race on platforms without atomics
1.8.0
Add try_insert API -- a version of set that returns a reference.
1.7.2
Improve code size when using parking_lot feature.
1.7.1
Fix race::OnceBox<T> to also impl Default even if T doesn't impl Default.
1.7.0
Hide the race module behind (default) race feature.
Turns out that adding race by default was a breaking change on some platforms without atomics.
In this release, we make the module opt-out.
Technically, this is a breaking change for those who use race with no_default_features.
Given that the race module itself only several days old, the breakage is deemed acceptable.
1.6.0
Add Lazy::into_value
Stabilize once_cell::race module for "first one wins" no_std-compatible initialization flavor.
Migrate from deprecated compare_and_swap to compare_exchange.
1.5.2
OnceBox API uses Box<T>.
This a breaking change to unstable API.
