Changing #[repr(u32)] to #[repr(i32)] and certificateType: self.certificate_type as u32 to certificateType: self.certificate_type as i32 fixed this for me, but I don't understand why they were u32 in the first place - is it an OS difference? I'm on Windows x64

It looks like bindgen generates u32 for C enum values on Linux/macOS but i32 for windows ...
I'll look into it.

@WilliamVenner I pushed a fix on master, could you give it a try and let me know whether it works for you on Windows ?

[lerouxrgd]

It should be fixed in 0.6.3
