| help: within `{coroutine@$DIR/drop-yield-twice.rs:7:30: 7:32}`, the trait `Send` is not implemented for `Foo` |
| --> $DIR/drop-yield-twice.rs:3:1 |
| | |
| LL | struct Foo(i32); |
| | ^^^^^^^^^^ |
| note: coroutine is not `Send` as this value is used across a yield |
| --> $DIR/drop-yield-twice.rs:9:9 |
| | |
| LL | let guard = Foo(42); |
| | ----- has type `Foo` which is not `Send` |
| LL | yield; |
| | ^^^^^ yield occurs here, with `guard` maybe used later |
| note: required by a bound in `assert_send` |
