Make SendResult more general to use

[aCoder2013]

Currently SendResult's messageId is a String , in my case ,message id is a object with custom field ,i wonder if it can be a generic type like SendResult<T> ? Thanks for you time

public interface SendResult {
    /**
     * The unique message id related to the {@code SendResult} instance.
     *
     * @return the message id
     */
    String messageId();
}

Are the custom fields stored in some place?

@zhouxinyu The messageId is actually a protobuf object , so i choose to transfer it into a base64 string
