#[derive(MultipartForm)]
struct Upload {
    description: Option<Text<String>>,
    timestamp: Text<i64>,
    #[multipart(rename="image_set[]")]

• Receiving optional fields, using Option.
• Receiving lists of fields, using Vec<T>.
• Deserialize integers, floats, enums from plain text fields using Text<T>.
• Deserialize complex data from JSON uploads, using Json<T>.
• Receive file uploads into temporary files on disk, using Tempfile.
• User customisable asynchronous field readers, for example you may want to stream form data to an object storage service, just implement the FieldReader trait.

• Pull request to add this to actix-multipart
