Concept definition

    template<class T>
    concept string_like = std::convertible_to<const T&, std::basic_string_view<char>>
          or std::convertible_to<const T&, std::basic_string_view<wchar_t>>
          or std::convertible_to<const T&, std::basic_string_view<char8_t>>
          or std::convertible_to<const T&, std::basic_string_view<char16_t>>
          or std::convertible_to<const T&, std::basic_string_view<char32_t>>

Detailed Description

Template Parameters

T	The type to be checked.

The string_like concept is satisfied when a const object of type T is implicitly convertible to a std::basic_string_view of char, wchar_t, char8_t, char16_t, or char32_t, as the standard strings and the string views are. It is used to detect the strings, which the formatter writes as text, not element by element (see formattable_range). A container that has only a member named npos, or that is not convertible, is not a string.
