Description
I hit a snag with lifetimes and wondered: is it intentional that WalkDir.sort_by_key requires a 'static lifetime on its func argument instead of just the same lifetime as the WalkDir?
I was trying to do something like this:
let walker = WalkDir::new(path)
.sort_by_key(|e| {
let relative_path = e.path().strip_prefix(path).unwrap();
some_func(relative_path)
})
…and that failed saying my path didn't live long enough for the required 'static lifetime, even though it does live until after walker was used and dropped.
