G-d willing

Hello,  
I would like to know how to write a generic function that accepts a data type and prints out the fields’ names and their types.  
How can I do this?

Thanks

Hi @cohen.avraham , Daml does not have reflection features of this kind. Even getting the human readable type name of a value is supported only in “dev” versions and for interfaces. See [How to get the name of a template or data type](https://discuss.daml.com/t/how-to-get-the-name-of-a-template-or-data-type/7314).
