Hello Adam, thank you for your great blog, it has been really useful.
As a follow-up, how do you think i can now extract from the MultipartStream

• file_name
• content_type

when i start extracting content before the stream macro i get an error of

cannot return value referencing local data self.0

 impl MultipartStream {
    pub async fn into_stream(
        mut self,
    ) -> impl Stream<Item = Result<Bytes, MultipartError>> {
        let field = self.0.next_field().await.unwrap().unwrap();
        let file_name = field.file_name().unwrap().to_string();
        let content_type = field.content_type().unwrap().to_string();
        async_stream::stream! {
            for await value in field {
                yield value;
            }
        }
    }
}

the idea was to return those values as a struct or tuple.

What i can see is that the file_name needs to be retrieved outside of the async_stream::stream! as those attribute are needed before actually streaming.

Thank you!!
