impl<'a> FusedIterator for SplitAsciiWhitespace<'a> {}Original feature request:
Considering how is_ascii_whitespace is now available on libcore, it makes sense to provide this too.
I'll provide a PR at some point if this seems reasonable; a lot of code that needs to split on whitespace only needs to split on ASCII whitespace, which is considerably faster.
