Time to
cargo rm once_cell!Thank you and goodbye to
lazy-static, I'll think of you every time I use a regex.You may be interested in
lazy-regex.
Immediately used the LazyLock +
staticto build a quasi-constant which does an expensive check only once at program start, and only when it's actually used. Pretty cool.It's really nice how you can now iterate over a boxed slice using
for x in &yrather than being forced to usefor x in y.iter().
