Should serde_as apply default when the field is of type Option<_> #185
Description
Using deserialize_with or serde_as on a Option field makes them mandatory while deserializing. In order to make the behavior match more closely with the default serde behavior, serde_as could apply the default attribute on the field. This would make the field optional again while deserializing.
The downside would be that is complicates the macro and would introduce additional behavior.
Right now it only translates the serde_as attribute into serde's deserialize_with and serialize_with.
