Can the new `std::sync::OnceLock` replace `once_cell::sync::OnceCell`?

Or what's the difference?

The once_cell crate uses modules to separate the thread safe and non-thread safe versions, but the types have the same names within those modules. The std versions have different names as well as being in different modules. OnceCell for the non-thread safe version and OnceLock for the thread safe version. This makes the types more consistent with the naming scheme of other types in std.


Or is the difference only naming? Then for new projects I will use the std version.

They aren't perfectly identical API wise, but the fundamental operations should work the same.
