Detailed Description

template<typename Derived>
class vccc::ranges::view_interface< Derived >

Public Types
using	$vccc_derived = Derived

Public Member Functions
empty
returns whether the derived view is empty. Provided if it satisfies sized_range or forward_range.
template<typename D = Derived, std::enable_if_t< sized_range< D >::value, int > = 0>
constexpr bool	empty ()
template<typename D = Derived, std::enable_if_t< conjunction< negation< sized_range< D >>, forward_range< D > >::value, int > = 0>
constexpr bool	empty ()
template<typename D = Derived, std::enable_if_t< sized_range< const D >::value, int > = 0>
constexpr bool	empty () const
template<typename D = Derived, std::enable_if_t< conjunction< negation< sized_range< const D >>, forward_range< const D > >::value, int > = 0>
constexpr bool	empty () const
cbegin
returns a constant iterator to the beginning of the range.
constexpr auto	cbegin ()
template<typename D = Derived, std::enable_if_t< range< const D >::value, int > = 0>
constexpr auto	cbegin () const
cend
returns a sentinel for the constant iterator of the range.
constexpr auto	cend ()
template<typename D = Derived, std::enable_if_t< range< const D >::value, int > = 0>
constexpr auto	cend () const
operator bool
returns whether the derived view is not empty. Provided if ranges::empty is applicable to it.
template<typename D = Derived, std::enable_if_t< detail::is_empty_callable< D & >::value, int > = 0>
constexpr	operator bool ()
template<typename D = Derived, std::enable_if_t< detail::is_empty_callable< const D & >::value, int > = 0>
constexpr	operator bool () const
data
gets the address of derived view's data. Provided if its iterator type satisfies contiguous_iterator.
template<typename D = Derived, std::enable_if_t< detail::check_vi_data< D >::value, int > = 0>
constexpr auto	data ()
template<typename D = Derived, std::enable_if_t< detail::check_vi_data< const D >::value, int > = 0>
constexpr auto	data () const
size
returns the number of elements in the derived view. Provided if it satisfies forward_range and its sentinel and iterator type satisfy sized_sentinel_for.
template<typename D = Derived, std::enable_if_t< detail::check_vi_size< D >::value, int > = 0>
constexpr auto	size ()
template<typename D = Derived, std::enable_if_t< detail::check_vi_size< const D >::value, int > = 0>
constexpr auto	size () const
front
returns the number of elements in the derived view. Provided if it satisfies forward_range and its sentinel and iterator type satisfy sized_sentinel_for.
template<typename D = Derived, std::enable_if_t< forward_range< D >::value, int > = 0>
constexpr decltype(auto)	front ()
template<typename D = Derived, std::enable_if_t< forward_range< const D >::value, int > = 0>
constexpr decltype(auto)	front () const
back
returns the last element in the derived view. Provided if it satisfies bidirectional_range and common_range. The default implementation of back() member function returns the last element in the view of the derived type. Whether the element is returned by value or by reference depends on the operator* of the iterator type.
template<typename D = Derived, std::enable_if_t< conjunction< bidirectional_range< D >, common_range< D > >::value, int > = 0>
constexpr decltype(auto)	back ()
template<typename D = Derived, std::enable_if_t< conjunction< bidirectional_range< const D >, common_range< const D > >::value, int > = 0>
constexpr decltype(auto)	back () const
operator[]
returns the \( { N^{th}} \) element in the derived view. Provided if it satisfies random_access_range. The default implementation of operator[] member function obtains the element at the specified offset relative to the beginning iterator, reusing the operator[] of the iterator type.
template<typename R = Derived, std::enable_if_t< random_access_range< R >::value, int > = 0>
constexpr decltype(auto)	operator[] (range_difference_t< R > n)
template<typename R = const Derived, std::enable_if_t< random_access_range< R >::value, int > = 0>
constexpr decltype(auto)	operator[] (range_difference_t< R > n) const
