Support for aud field accepting both a String and a List of Strings

[hvdrumsta]

Hi there, according to JWT spec, the aud could be either an array of Strings or if it's a single element it could be just a String that's not inside a list.

I was wondering how to decode a JWT into a claims structure that could accept both a List of String and a single String?

You will need to make the aud an enum like in https://github.com/Keats/jsonwebtoken/blob/master/src/validation.rs#L181-L186

This library already handles both cases

Thank you, that worked.
