error[E0277]: `()` doesn't implement `std::fmt::Display`

LL |     let x = foo::<()>;
   |                   ^^ `()` cannot be formatted with the default formatter
   |
   = 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`
