bikeshed: It is interesting that the standard library has renamed this to OnceLock.

Interesting, it looks like the name is very much in flux for std right now. Do we wait for libstd to arrive at a proper conclusion, or do we just keep OnceCell?

OnceCell seems good to me. Other crates use the same name as well.

@taiki-e Any thoughts on this? Right now this requested change is blocking the merge.

Future notes: OnceLock was decided on the final name by libstd. It might be prudent to rename OnceCell appropriately at the next breaking change.

@smol-rs/admins Don't release this yet. I'd like event-listener#30 to be completed so that the changes there can be reflected in the new APIs, to prevent any major version bumps being necessary. |

I guess adding no-std support to this crate would require a major version bump anyway. (no-std support would be a breaking change for users who disable the default features) |
This PR adds a
OnceCelltype similar to the types found in theonce_cellcrate and thetokiocrate. It is usable from both blocking and non-blocking code.
