error[E0382]: borrow of moved value: `g`
--> $DIR/issue-105084.rs:37:14
|
LL | let mut g = || {
| ----- move occurs because `g` has type `{coroutine@$DIR/issue-105084.rs:14:17: 14:19}`, which does not implement the `Copy` trait
...
LL | let mut h = copy(g);
| - value moved here
...
LL | Pin::new(&mut g).resume(());
| ^^^^^^ value borrowed here after move
|
note: consider changing this parameter type in function `copy` to borrow instead if owning the value isn't necessary
--> $DIR/issue-105084.rs:9:21
|
LL | fn copy<T: Copy>(x: T) -> T {
| ---- ^ this parameter takes ownership of the value
| |
| in this function
help: consider cloning the value if the performance cost is acceptable
|
LL | let mut h = copy(g.clone());

error[E0277]: the trait bound `Box<(i32, ())>: Copy` is not satisfied in `{coroutine@$DIR/issue-105084.rs:14:17: 14:19}`
--> $DIR/issue-105084.rs:31:17

LL | let mut g = || {

...
LL | let mut h = copy(g);
| ^^^^ within `{coroutine@$DIR/issue-105084.rs:14:17: 14:19}`, the trait `Copy` is not implemented for `Box<(i32, ())>`
|
note: coroutine does not implement `Copy` as this value is used across a yield
--> $DIR/issue-105084.rs:21:22

LL | Box::new((5, yield));
| -------------^^^^^--
| | |
| | yield occurs here, with `Box::new((5, yield))` maybe used later
| has type `Box<(i32, ())>` which does not implement `Copy`
note: required by a bound in `copy`
--> $DIR/issue-105084.rs:9:12

LL | fn copy<T: Copy>(x: T) -> T {
