A successful advance is now signalled by returning `0` and other values now represent the remaining number of steps that couldn't be advanced as opposed to the amount of steps that have been advanced during a partial advance_by. This simplifies adapters a bit, replacing some `match`/`if` with arithmetic. Whether this is beneficial overall depends on whether `advance_by` is mostly used as a building-block for other iterator methods and adapters or whether we also see uses by users where `Result` might be more useful. |
