error[E0277]: the trait bound `Bar: Copy` is not satisfied
--> $DIR/fn-call-in-non-const.rs:14:32
|
LL | let _: [Option<Bar>; 2] = [no_copy(); 2];
| ^^^^^^^^^ the trait `Copy` is not implemented for `Bar`
|
= note: required for `Option<Bar>` to implement `Copy`
= note: the `Copy` trait is required because this value will be copied for each element of the array
= help: consider creating a new `const` item and initializing it with the result of the function call to be used in the repeat position, like `const VAL: Type = const_fn();` and `let x = [VAL; 42];`
= help: create an inline `const` block, see RFC #2920 <https://github.com/rust-lang/rfcs/pull/2920> for more information
help: consider annotating `Bar` with `#[derive(Copy)]`
|
LL + #[derive(Copy)]
LL | struct Bar;
|
error: aborting due to previous error
