error[E0107]: function takes 0 generic arguments but 1 generic argument was supplied
--> $DIR/issue-100154.rs:4:5
|
LL | foo::<()>(());
| ^^^------ help: remove these generics
| |
| expected 0 generic arguments
|
note: function defined here, with 0 generic parameters
--> $DIR/issue-100154.rs:1:4
|
LL | fn foo(i: impl std::fmt::Display) {}
| ^^^
= note: `impl Trait` cannot be explicitly specified as a generic argument
error[E0277]: `()` doesn't implement `std::fmt::Display`
--> $DIR/issue-100154.rs:4:15
|
LL | foo::<()>(());
| --------- ^^ `()` cannot be formatted with the default formatter
| |
| required by a bound introduced by this call
|
= help: the trait `std::fmt::Display` is not implemented for `()`
= note: in format strings you may be able to use `{:?}` (or {:#?} for pretty-print) instead
note: required by a bound in `foo`
--> $DIR/issue-100154.rs:1:16
|
LL | fn foo(i: impl std::fmt::Display) {}
| ^^^^^^^^^^^^^^^^^ required by this bound in `foo`
error: aborting due to 2 previous errors
