   4 ==============================

   6 Optimize calls to ``std::string::find()`` and friends when the needle passed is
   7 a single character string literal. The character literal overload is more
   8 efficient.

  10 Examples:

  12 .. code-block:: c++
  13
  14   str.find("A");
  15
  16   // becomes

  18   str.find('A');

  25    Semicolon-separated list of names of string-like classes. By default only
  26    ``::std::basic_string`` and ``::std::basic_string_view`` are considered.
  27    The check will only consider member functions named ``find``, ``rfind``,
  28    ``find_first_of``, ``find_first_not_of``, ``find_last_of``, or
  29    ``find_last_not_of`` within these classes.
