error[E0277]: `NoDisplay` doesn't implement `std::fmt::Display`
--> tests/ui/printdoc-no-display.rs:6:21
|
6 | printdoc!("{}", NoDisplay);
| ^^^^^^^^^ `NoDisplay` cannot be formatted with the default formatter
|
= help: the trait `std::fmt::Display` is not implemented for `NoDisplay`
= note: in format strings you may be able to use `{:?}` (or {:#?} for pretty-print) instead
= note: this error originates in the macro `$crate::format_args` (in Nightly builds, run with -Z macro-backtrace for more info)
