class basic_string_view

Declaration

template <typename Char>
class basic_string_view { /* full declaration omitted */ };

Description

An implementation of ``std::basic_string_view`` for pre-C++17. It provides a subset of the API. ``fmt::basic_string_view`` is used for format strings even if ``std::string_view`` is available to prevent issues when a library is compiled with a different ``-std`` option than the client code (which is not recommended).
