not sure what's going on, might be ctor or this library or neither? also opened mmastrac/rust-ctor#219

[ChrisDenton]

Hi, this is likely caused by the ctor. Rust std currently uses a ctor to load some functions. So if other code also runs in a ctor it's possible that it runs before the std ctor. This would cause it to think the function couldn't be loaded.

This should be fixed in Rust's std to ensure this does not happen. I'll submit a patch to Rust as soon as I'm able.

[brandonros]

No problem. Thanks. If that helps at all, it's as if NtWriteFile is getting dropped by the linker or something?

Is there a way I could make my ctor fire after the Rust std ctor? I've had this code working before. It recently changed when I switched to workspace modules, etc.

[brandonros]

will continue the issue in ctor since it is a better fit
