Make RSplit<T, P>: Clone not require T: Clone This addresses a TODO comment. The behavior of `#[derive(Clone)]` *does* result in a `T: Clone` requirement. Playground example: https://play.rust-lang.org/?version=stable&mode=debug&edition=2018&gist=a8b1a9581ff8893baf401d624a53d35b Add a manual `Clone` implementation, mirroring `Split` and `SplitInclusive`. `(R)?SplitN(Mut)?` don't have any `Clone` implementations, but I'll leave that for its own pull request.
