FFI Compatible structs #453

Closed owenshoemaker closed 10 months ago

owenshoemaker commented 10 months ago

Is it possible to return an FFI compatible struct from a foreign_class method? I have tried a number of approaches and haven't had any success and can't find any documentation.

I am just trying to return something like this:

[repr(C)]

pub struct SimpleStruct { pub my_string: *const c_char, }

I just get the "Do not know conversion from such rust type" error.

You can find example here:

That did the trick. I just needed to use: "*const ::std::os::raw::c_char".

Thanks!
