Compiling rectangles v0.1.0 (file:///projects/rectangles)
|

error[E0277]: `Rectangle` doesn't implement `std::fmt::Display`
|
|
--> src/main.rs:12:29
|
|
|
|
|
12 | println!("rect1 is {}", rect1);
|
|
| ^^^^^ `Rectangle` cannot be formatted with the default formatter
|
|
|
|
|
= help: the trait `std::fmt::Display` is not implemented for `Rectangle`
|
|
= 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_nl` which comes from the expansion of the macro `println` (in Nightly builds, run with -Z macro-backtrace for more info)
