error[E0185]: method `example` has a `&self` declaration in the impl, but not in the trait
  --> $DIR/argument_number_mismatch_ice.rs:8:5
   |
LL |     fn example(val: ());
   |     -------------------- trait method declared without `&self`
...
LL |     fn example(&self, input: &i32) {
   |     ^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^ `&self` used in impl

error[E0594]: cannot assign to `*input`, which is behind a `&` reference
  --> $DIR/argument_number_mismatch_ice.rs:10:9
   |
LL |         *input = self.0;
   |         ^^^^^^^^^^^^^^^ `input` is a `&` reference, so the data it refers to cannot be written
   |
help: consider changing this to be a mutable reference in the `impl` method and the `trait` definition
   |
LL |     fn example(&self, input: &mut i32) {
