error: future cannot be sent between threads safely
--> tests/cxx_string.rs:14:5
|
13 | fn assert_send(_: impl Send) {}
| ---- required by this bound in `assert_send`
14 | assert_send(f());
| ^^^^^^^^^^^ future returned by `f` is not `Send`
|
= help: within `impl Future`, the trait `Send` is not implemented for `*const ()`
note: future is not `Send` as this value is used across an await
--> tests/cxx_string.rs:9:9
|
6 | let_cxx_string!(s = "...");
| --------------------------- has type `StackString` which is not `Send`
...
9 | g(&s).await;
| ^^^^^^^^^^^ await occurs here, with `mut $var` maybe used later
10 | }
| - `mut $var` is later dropped here
