I’ve been using lazy_static until now but was trying to migrate to OnceCell. It seems I can’t have a OnceCell<Regex> even though I’m never calling mutable methods on the regex. I’m not even using multiple threads.

The error I’m getting is:

Any way to solve this or do I have to use OnceLock / continue using lazy_static? I don’t want to add the overhead of using OnceLock if not necessary.

    Yeah, it doesn’t help that in the once_cell crate, the thread-safe version was also called OnceCell; you had to choose between once_cell::sync::OnceCell and once_cell::unsync::OnceCell. But when it was added to the standard library, once_cell::sync::OnceCell was renamed to OnceLock to make them easier distinguishable. So
