Sorry for the long log or if I posted to the wrong place.

Please check your Rust version. The library is compatible with nightlies, and struct_variants feature guard has been removed almost two weeks ago. Consequently there is no need for this feature gate now.

Thank you.
I was using nightly. Switching to the 32bit version of Rust fixed the problem.

That's strange because nightly builder for win64 seems to be working correctly, and its last build was today. You could try downloading win64 build again.
