How to modify response body using middleware?

[oldtune]

Hi, i'm trying to standadize my API response to something like this

BaseResponse<T> where T: Serialize{
Success: bool,
Data: T,
Error: Vec<String>,
}

but not sure how to extract the response body and wrap it inside the call function

fn call(&self, req: ServiceRequest) -> Self::Future {
        let fut = self.service.call(req);

        Box::pin(async move {
            let mut res = fut.await?;
              //Having no clue how to unwrap the body and wrap it in BaseResponse here
            Ok(res)
        })
    }

I've been scratching my head on Google and StackOverflow but still can't figure out how to make it work, can you show me if it's possible?
