🦀 winresult - windows result codes 🦀

Debug-friendly types for windows result codes.

Why?

• u32 error codes are annoying to dbg!(...). winresult has awesome Debug impls.

• u32 error codes are annoying to view in your debugger. winresult has awesome *.natvis files. Use natvis-pdbs!

• typoing ERROR_WHATEVER in a match is a mere warning. ERROR::WHATEVER is a hard error.
  (I'd still use #![deny(unreachable_patterns)] anyways.)

• ERROR_INVALID_FUNCTION == S_FALSE (== 1.) Lame!

• ERROR_FILE_NOT_FOUND (2) is a mess. A function or GetLastError might return:

  label	value	notes
  ERROR_FILE_NOT_FOUND	0x00000002	Not an HRESULT (would be "successful")
  HRESULT_FROM_WIN32(ERROR_FILE_NOT_FOUND)	0x80070002	hresult.info "incorrectly" labels ERROR_* as this
  NTSTATUS_FROM_WIN32(ERROR_FILE_NOT_FOUND)	0xC0070002	IDK how frequently NtStatuses get shoved into GetLastError, but I've seen weirder
  D3D10_ERROR_FILE_NOT_FOUND	0x88790002	Different facility, same code
  D3D11_ERROR_FILE_NOT_FOUND	0x887C0002	Different facility, same code

• ERROR_* is a mixture of HRESULTs and non-HRESULTs. Can you keep them straight? No. No you cannot. Stop lying.
