How to decode Structures with optional fields

[May1592]

Hi @magiconair @kung-foo ,
I don't see support for decoding structure with optional fields. In below screenshot , it's a custom structure with optional fields and while we decode this we should skip these struct fields since Encoding mask is zero.

Please suggest.

We don't have direct support for optional fields. You need to define your structure with the correct EncodingMask. Check similar structures in the ua package. I'm open for suggestions on what good support for optional fields should look like.

Based On EncodingMask, we will know which optional field is available and which is not. Optional Field which is not available will be null.
Hence in decoding logic we need to take care if Optional field is present or null.
@magiconair your thought on how to build logic for decoding optional field?
