Detailed Description

template<typename Char>
class basic_cstring_view< Char >

\rst A reference to a null-terminated string. It can be constructed from a C string or std::string.

You can use one of the following type aliases for common character types:

+------------—+--------------------------—+ | Type | Definition | +===============+=============================+ | cstring_view | basic_cstring_view<char> | +------------—+--------------------------—+ | wcstring_view | basic_cstring_view<wchar_t> | +------------—+--------------------------—+

This class is most useful as a parameter type to allow passing different types of strings to a function, for example::

template <typename... Args> std::string format(cstring_view format_str, const Args & ... args);

format("{}", 42); format(std::string("{}"), 42); \endrst
