##### Static Members

Name | Description
--- | ---
npos | A special index.
static_capacity | Maximum size of the string excluding any null terminator.

##### Description

These objects behave like `std::string` except that the storage is not dynamically allocated but rather fixed in size, and stored in the object itself. These strings offer performance advantages when an algorithm can execute with a reasonable upper limit on the size of a value.

##### Aliases

The following alias templates are provided for convenience:

    template <std:: size_t N>
    using static_string =
      basic_static_string<N, char, std::char_traits<char>>;

    template <std:: size_t N>
    using static_wstring =
      basic_static_string<N, wchar_t, std::char_traits<wchar_t>>;

    template <std:: size_t N>
    using static_u16string =
      basic_static_string<N, char16_t, std::char_traits<char16_t>>;

    template <std:: size_t N>
    using static_u32string =
      basic_static_string<N, char32_t, std::char_traits<char32_t>>;

Addtionally, the alias template `static_u8string` is provided in C++20

    template <std:: size_t N>
    using static_u8string =
      basic_static_string<N, char8_t, std::char_traits<char8_t>>;
