I would appreciate some help with my poor understanding of the type system... ``` let mut client = db_pool.get().await?.deref_mut().deref_mut(); let report = embedded::migrations::runner() .run_async(&mut client) .await?; ``` using deadpool with tokio-postgres and I get the following compile error (that I do not understand, really :) ``` the trait `refinery::AsyncMigrate` is not implemented for `&mut tokio_postgres::client::Client` ```
