error: coroutine cannot be sent between threads safely
--> $DIR/drop-yield-twice.rs:7:5
|
LL | / assert_send(#[coroutine] || {
LL | | let guard = Foo(42);
LL | | yield;
LL | | drop(guard);
LL | | yield;
LL | | })
| |______^ coroutine is not `Send`
|
help: within `{coroutine@$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`
--> $DIR/drop-yield-twice.rs:15:19
|
LL | fn assert_send<T: Send>(_: T) {}
| ^^^^ required by this bound in `assert_send`
error: aborting due to 1 previous error
