SystemErrorCode

A tagged union that holds an error code from system apis, meaning one from Windows GetLastError() or C's errno.

You construct it with SystemErrorCode(thing) and the overloaded constructor tags and stores it.

struct SystemErrorCode {

this(int errno);

this(uint win32);

bool wasSuccessful();

string toString();

string codeAsString();

string errorString();

}

Constructors

this this(int errno)
this(uint win32): C/unix error are typed as signed ints... Windows' errors are typed DWORD, aka unsigned...
