Detailed Description

Implements sstring_view, a class which is based on std::string_view but holds a pointer which may be a std::shared_ptr<char> or std::unique_ptr<char> as well has a raw pointer.

This class is intended to improve the performance of the string set – where it avoids the construction of std::string instances – and to enable string values from the database and in-memory string values to be used interchangably.
