2 Checks for usages of `str::splitn` (or `str::rsplitn`) where using `str::split` would be the same.
4 The function `split` is simpler and there is no performance difference in these cases, considering
5 that both functions return a lazy iterator.
8 let str = "key=value=add";
9 let _ = str.splitn(3, '=').next().unwrap();
14 let str = "key=value=add";
15 let _ = str.split('=').next().unwrap();
