Function error_code_from_win32 

pub fn error_code_from_win32(code: u32) -> ErrorCode

The code a Win32 error names, wrapped as HRESULT_FROM_WIN32 wraps it: a value that is already an HRESULT – zero, or one with the severity bit set – is taken as it is, and any other keeps only its low sixteen bits. The rule is win-error-codes’s (HResult::from_win32); the number space is this crate’s, since the codes this driver reports are HRESULTs.
