Function errorToBool

ext/include/llvm/Support/Error.h:1024–1029

Helper for converting an Error to a bool. This method returns true if Err is in an error state, or false if it is in a success state. Puts Err in a checked state in both cases (unlike Error::operator bool(), which only does this for success states).

/// in a success state.  Puts Err in a checked state in both cases (unlike
/// Error::operator bool(), which only does this for success states).
inline bool errorToBool(Error Err) {
  bool IsError = static_cast<bool>(Err);
  if (IsError)
    consumeError(std::move(Err));
  return IsError;
}
