error[E0277]: `T` doesn't implement `std::fmt::Display`
--> $DIR/bounds-are-checked3.rs:9:35
|
LL | type Foo<T: Debug> = (impl Debug, Struct<T>);
| ^^^^^^^^^ `T` cannot be formatted with the default formatter
|
= note: in format strings you may be able to use `{:?}` (or {:#?} for pretty-print) instead
note: required by a bound in `Struct`
--> $DIR/bounds-are-checked3.rs:5:18
|
LL | struct Struct<V: Display>(Option<V>);
| ^^^^^^^ required by this bound in `Struct`
help: consider further restricting type parameter `T` with trait `Display`
|
LL | type Foo<T: Debug + std::fmt::Display> = (impl Debug, Struct<T>);
