Access fields data

See original GitHub issue

Hi again,

So I encountered an issue when trying to integrate msgspec into the internal of our libraries, namely - there is no way for me to easily access the field information on a struct.

The __struct_fields__ attribute only offers a tuple of field names. If I want to access the metadata regarding each field I have to result to some rather inefficent methods such as inspecting the attributes, which is very slow.

I would like to regard a simple and fast way to get the following information about a field: its typing, any default value defined for it, and other meta data available.

so, any plans on adding this utility?

Yes, it just may take a bit. This is purely a hobby project done on my own time.

I understand. We also develop Starlite as a “hobby” - although a very serious one. This is the main blocker for us to migrate our internal parsing mechanism to using msgspec, which we are pretty eager on. Lemme know if there is anything I can help with.
