Detailed Description

Encapsulates an std::istream for a StringView.

Currently (C++20) std::istringstream uses an std::string for input, which requires an instance of this type and thus a potential allocation. This class serves to avoid this by directly using the memory pointed to by the instance of StringView passed in the constructor. The latter must remain valid throughout the use of this class.
