error[E0277]: expected a `FnMut<(char,)>` closure, found `u8`
--> $DIR/assoc-fn-bound-root-obligation.rs:2:20
|
LL | s.strip_suffix(b'\n').unwrap_or(s)
| ------------ ^^^^^ expected an `FnMut<(char,)>` closure, found `u8`
| |
| required by a bound introduced by this call
|
= 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 because of the requirements on the impl of `Pattern<'_>` for `u8`
error: aborting due to previous error
