How do I get the size of the ServiceResponse body?

[SamuelMarks]

Expected Behavior

You can see my debug code here, the test succeeds but I'm unable to trivially determine the size of the body (I want to; in my test; check it's 0)

let resp = actix_web::test::call_service(&app, test_profile_api::remove(&token)).await;
    let headers = resp.headers();
    println!("{:#?}", resp.response.body());
    assert_eq!(
        resp.status(),
        actix_web::http::StatusCode::from_u16(204u16).unwrap()
    );

Current Behavior

It's not in the header (Content-Size I was seeking) or elsewhere.

Possible Solution

resp.into_body().try_into_bytes().unwrap()

Then guess I can call .next() repetitevly to confirm the size is greater than 0

Steps to Reproduce (for bugs)

• https://docs.rs/actix-web/latest/actix_web/body/trait.MessageBody.html#tymethod.size
• https://docs.rs/actix-web/latest/actix_web/body/enum.BodySize.html

use actix_web::body::MessageBody as _;
res.response().body().size()

the content-length header is set much later, using info from this method
