error[E0277]: the trait bound `U1: Copy` is not satisfied
--> $DIR/union-derive-clone.rs:6:10
|
LL | #[derive(Clone)]
| ^^^^^ the trait `Copy` is not implemented for `U1`

note: required by a bound in `AssertParamIsCopy`
--> $SRC_DIR/core/src/clone.rs:LL:COL

LL | pub struct AssertParamIsCopy<T: Copy + ?Sized> {
| ^^^^ required by this bound in `AssertParamIsCopy`
= note: this error originates in the derive macro `Clone` (in Nightly builds, run with -Z macro-backtrace for more info)
help: consider annotating `U1` with `#[derive(Copy)]`
