| LL | s.strip_suffix(b'\n').unwrap_or(s) |
| | ^^^^^^^^^^^^ expected an `FnMut(char)` closure, found `u8` |
| | |
| = help: the trait `FnMut<(char,)>` is not implemented for `u8`, which is required by `u8: Pattern<'_>` |
| = help: the following other types implement trait `Pattern<'a>`: |
| char |
| [char; N] |
| &'b String |
| &'b [char; N] |
| &'b [char] |
| &'c &'b str |
| &'b str |
| = note: required for `u8` to implement `Pattern<'_>` |
