// AuditLogChange is a single key type to changed value audit log entry. The

//
// What
//
// I'm glad to see the same reaction that I had on you. In short, in this
// struct, the Key dictates what type NewValue and OldValue will have. They will
// always be the same type, but I will leave that as JSON for the user.
//
// Usage
//
// The usage of this is pretty simple, as AuditLogChange already has a
// convenient method to use. Here's an example on how to do "owner_id":
//
//    if change.Key != discord.AuditGuildOwnerID {
//        return errors.New("not owner ID")
//    }
//
//    // We know these are UserIDs because the comment said so for AuditGuildOwnerID.
//    var oldOwnerID, newOwnerID discord.UserID
//    if err := change.UnmarshalValues(&oldOwnerID, &newOwnerID); err != nil {
//        return err
//    }
//
//    log.Println("Transferred ownership from user", oldOwnerID, "to", newOwnerID)
//
