warning: use of `async fn` in public traits is discouraged as auto trait bounds cannot be specified

22 |   async fn fn_action(
   |   ^^^^^

   = 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: `#[warn(async_fn_in_trait)]` on by default
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
