Lifetimes do not match method in trait

[simonsan]

Describe the bug

When you copy one of the examples or in general use the 'implement missing members' of rust-analyzer you'll get error[E0195]: lifetime parameters or bounds on method '<method>' do not match the trait declaration. This could be related to the removal of async_trait, I assume?

To Reproduce Steps to reproduce the behaviour:

1. Copy example into crates main.rs
2. run cargo check
3. See above error.

Expected behaviour It works without manually researching on the error.

The reason is you haven't disabled the use of the async-trait feature on ractor, which is a default feature. If you want to use the new async fn in traits functionality, you have to bring ractor to the same.

The default mode, in order to not break backwards compatibility and while we assess the impact of not boxing the futures, is to continue using async-trait for the time being
