--> $DIR/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: required by `std::fmt::Display::fmt`
= note: this error originates in a macro (in Nightly builds, run with -Z macro-backtrace for more info)
