Post a tar archive in a reqwest function

Question

Hi i want to send a tar archive with a docker image to docker build api. this is an example of how i am triyng to post that

// build image
pub fn build_image_fn(docker_api_ip: &str, image_name: &str, img_file_path: &str) -> Result<String, Error> {
  let client = Client::new();
  // read the tar
  let file = File::open(img_file_path).unwrap();
  println!("path: {img_file_path}");
  // post
  let url = format!("http://{docker_api_ip}/build?t={image_name}");
  let response = client
    .post(url)
    .header("Content-Type", "application/tar")
    .body(file)
    .send();
  // Check if the request was successful
  match response {
    Ok(response) => {
      if response.status().is_success() {
        Ok("Image builded successfully".to_string())
      } else {
          let status = response.status().clone();
          let body = response.text().unwrap();
          let err = serde_json::from_str::<ApiErr>(&body).expect("failed to deserialize build_image_fn error json");
          let err_str = format!("Error: code:{}, message: {}", status, err.message);
          Ok(err_str)
      }
    }
    Err(err) => {
      Err(err)
    }
  }
}

if i do that with curl using --data-binary to send my tar, the image builds successfuly so i would like to see if there is something to replicate the behaviour of --data-binary but in rust reqwest
