Support pointer-sized struct arguments in callbacks (NewCallback) #418
Description
Operating System
- Windows
- macOS
- Linux
- FreeBSD
- Android
- iOS
What feature would you like to be added?
Allow callback argument types that are structs whose flattened leaf fields total exactly one pointer-sized slot (for example wrapper types with embedded unsafe.Pointer).
Why is this needed?
Generated bindings and Objective-C wrappers often model pointers as tiny structs. Today those callback signatures are rejected even when ABI-equivalent to a pointer-sized argument.

Can you provide an example of this in practice? If I understand correctly this is just implementing structs to be transparent if just contesting other structs for callbacks?

I think this is covered by completion of #225
