1 error: future cannot be sent between threads safely
2 --> $DIR/drop-track-field-assign-nonsend.rs:43:17
4 LL | assert_send(agent.handle());
5 | ^^^^^^^^^^^^^^ future returned by `handle` is not `Send`
7 = help: within `impl Future<Output = ()>`, the trait `Send` is not implemented for `Rc<String>`
8 note: future is not `Send` as this value is used across an await
9 --> $DIR/drop-track-field-assign-nonsend.rs:21:38
11 LL | let mut info = self.info_result.clone();
12 | -------- has type `InfoResult` which is not `Send`
14 LL | let _ = send_element(element).await;
15 | ^^^^^^ await occurs here, with `mut info` maybe used later
17 | - `mut info` is later dropped here
18 note: required by a bound in `assert_send`
19 --> $DIR/drop-track-field-assign-nonsend.rs:38:19
21 LL | fn assert_send<T: Send>(_: T) {}
22 | ^^^^ required by this bound in `assert_send`
