| error: use of `async fn` in public traits is discouraged as auto trait bounds cannot be specified |
| --> $DIR/warn.rs:6:5 |
| | |
| LL | async fn not_send(); |
| | ^^^^^ |
| | |
| = note: you can suppress this lint if you plan to use the trait only in your own code, or do not care about auto traits like `Send` on the `Future` |
| note: the lint level is defined here |
| --> $DIR/warn.rs:3:9 |
| | |
| LL | #![deny(async_fn_in_trait)] |
| | ^^^^^^^^^^^^^^^^^ |
| help: you can alternatively desugar to a normal `fn` that returns `impl Future` and add any desired bounds such as `Send`, but these cannot be relaxed without a breaking API change |
| | |
| LL - async fn not_send(); |
| LL + fn not_send() -> impl std::future::Future<Output = ()> + Send; |
| | |
| |
| error: aborting due to previous error |
