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

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

10Examples:
11
12.. code-block:: c++
13
14  str.find("A");
15
16  // becomes
17
18  str.find('A');

23.. option:: StringLikeClasses
24
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.
