More control when loading objects / Merely extending objects

[davidnorthetal]

Currently it seems whenever I load a single object from a file that specifies additional fields that don't correspond to any of the object an exception is thrown and it aborts.

I'm within a use-case where I wouldn't mind excessive fields in the file tho and would rather just skip them and proceed with loading whatever fields do fit.

AFAIS there's currently no way to achieve this.

Does ignoreInputKey help you?

[davidnorthetal]

Thanks for the quick response!

However, this would require me to know the fields names in advance, no? - I don't know them tho. People might just add arbitrary ones.

Well then we need an ignoreUnknownKeys :). I'll need to have a look whether that is easily implementable with the current compile-time infrastructure in the serialization module.

Things to do:

• Provide a macro ignoreUnknownKey
• Implement it for tuples (code pointer)
• Implement it for objects (code pointer)

I'll try to allocate time to do this, it seems like a useful addition. However, it's not trivial and may take some time.
