public member function

<string>

size_t max_size() const noexcept;

Return maximum size of string

This is the maximum potential length the string can reach due to known system or library implementation limitations, but the object is not guaranteed to be able to reach that length: it can still fail to allocate storage at any point before that length is reached.

size_t is an unsigned integral type (the same as member type string::size_type).
