error[E0277]: expected a `FnMut<(char,)>` closure, found `u8`
  --> $DIR/assoc-fn-bound-root-obligation.rs:2:7

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`
   = help: the following other types implement trait `Pattern<'a>`:
             &'b String
             &'b [char; N]
             &'b [char]
             &'b str
             &'c &'b str
             [char; N]
             char
   = note: required for `u8` to implement `Pattern<'_>`
