modify body in middleware

[piquu]

Summary

im trying to make a middleware that wraps the body in a template. i tried some solutions from stackoverflow and github issues but i cant get it to work properly.

pub async fn inject_base(request: Request, next: Next) -> Response {
    let response = next.run(request).await;
    let inject = !response.headers().contains_key("HX-Request");

    let (parts, body) = response.into_parts();
    let body = body::to_bytes(body, usize::MAX).await.unwrap();
    let body = String::from_utf8(body.to_vec()).unwrap();
    let body = Body::from(if inject {
        BaseTemplate {
            title: "",
            style: "",
            body,
        }.to_string()
    } else {
        body
    });

    Response::from_parts(parts, body)
}

the error im getting

payload claims content-length of 333, custom content-length header claims 56
