Beispiel #1

Datei: String.cpp Projekt: swirlycloud/swirly

pair<string_view, string_view> splitPair(string_view s, char delim) noexcept
{
  const auto pos = s.find_first_of(delim);
  string_view key, val;

  } else {
    key = s.substr(0, pos);
    val = s.substr(pos + 1);
  }
  return {key, val};
}
