Detailed Description

template<typename Char>
class basic_string_view< Char >

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::basic_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).
