Expected Behavior

Hi team, thank you for your extraordinaire work in the actix echo system!.

There's a featured I really needed to use while building an API route in actix but it seems to be in nonexistence yet.

I would like to be able to pass web::Json<T> (where T can match any json params passed to a req) instead of explicitly specifying T.

Will this be possible or perhaps it's already in existence ...?

Current Behavior

returns

the trait bound `JsonBody<_>: FromRequest` is not satisfied
required because of the requirements on the impl of `FromRequest` for `(Data<tokio_postgres::Client>, HttpRequest, JsonBody<_>)
