.. title:: clang-tidy - google-runtime-member-string-references
google-runtime-member-string-references
=======================================
Finds members of type ``const string&``.
const string reference members are generally considered unsafe as they can be
created from a temporary quite easily.
.. code-block:: c++
struct S {
S(const string &Str) : Str(Str) {}
const string &Str;
};
S instance("string");
In the constructor call a string temporary is created from ``const char *`` and
destroyed immediately after the call. This leaves around a dangling reference.
This check emit warnings for both ``std::string`` and ``::string`` const
reference members.
Corresponding cpplint.py check name: `runtime/member_string_reference`.
