The native package
The native package of the SDK contains nothing that should be
directly imported in a cross-platform application. It’s all platform-specific
support code for other parts of the SDK.
Windows
For example, the native/win32 package contains covers for types defined
in the Win32 API, along with a few error handling functions and other
things that are useful in the Win32 implementation of the SDK.
Note that there exists native sub packages elsewhere in the SDK, for example
in the io or in the os packages.
