This header is part of the ranges library.

Namespace aliases

Defined in header <ranges>
namespace std {     namespace view = ranges::view; }

The namespace alias std::view is provided as a shorthand for std::ranges::view.

Defined in header <ranges>
Defined in namespace std::ranges
Range access
ranges::begin (C++20)	returns an iterator to the beginning of a range (customization point object)
ranges::end (C++20)	returns a sentinel indicating the end of a range (customization point object)
ranges::rbegin (C++20)	returns a reverse iterator to a range (customization point object)
ranges::rend (C++20)	returns a reverse end iterator to a range (customization point object)
Range primitives
ranges::size (C++20)	returns an integer equal to the size of a range (customization point object)
ranges::empty (C++20)	checks whether a range is empty (customization point object)
ranges::data (C++20)	obtains a pointer to the beginning of a contiguous range (customization point object)
ranges::iterator_tranges::const_iterator_tranges::sentinel_tranges::const_sentinel_t (C++20)(C++23)(C++20)(C++23)	obtains iterator and sentinel types of a range (alias template)
Range concepts
ranges::range (C++20)	specifies that a type is a range, that is, it provides a begin iterator and an end sentinel (concept)
ranges::sized_range (C++20)	specifies that a range knows its size in constant time (concept)
ranges::view (C++20)	specifies that a range is a view, that is, it has constant time copy/move/assignment (concept)
ranges::input_range (C++20)	specifies a range whose iterator type satisfies input_iterator (concept)
ranges::output_range (C++20)	specifies a range whose iterator type satisfies output_iterator (concept)
ranges::forward_range (C++20)	specifies a range whose iterator type satisfies forward_iterator (concept)
ranges::bidirectional_range (C++20)	specifies a range whose iterator type satisfies bidirectional_iterator (concept)
ranges::random_access_range (C++20)	specifies a range whose iterator type satisfies random_access_iterator (concept)
ranges::contiguous_range (C++20)	specifies a range whose iterator type satisfies contiguous_iterator (concept)
ranges::common_range (C++20)	specifies that a range has identical iterator and sentinel types (concept)
ranges::viewable_range (C++20)	specifies the requirements for a range to be safely convertible to a view (concept)
Views
ranges::view_interface (C++20)	helper class template for defining a view, using the curiously recurring template pattern (class template)
ranges::subrange (C++20)	combines an iterator-sentinel pair into a view (class template)
Adaptors
views::all_tviews::all (C++20)	a view that includes all elements of a range (alias template) (range adaptor object)
ranges::filter_viewviews::filter (C++20)	a view that consists of the elements of a range that satisfies a predicate (class template) (range adaptor object)
ranges::transform_viewviews::transform (C++20)	a view of a sequence that applies a transformation function to each element (class template) (range adaptor object)
ranges::iota_viewviews::iota (C++20)	a view consisting of a sequence generated by repeatedly incrementing an initial value (class template) (customization point object)
ranges::take_viewviews::take (C++20)	a view consisting of the first N elements of another view (class template) (range adaptor object)
ranges::join_viewviews::join (C++20)	a view consisting of the sequence obtained from flattening a view of ranges (class template) (range adaptor object)
ranges::empty_viewviews::empty (C++20)	an empty view with no elements (class template) (variable template)
ranges::single_viewviews::single (C++20)	a view that contains a single element of a specified value (class template) (customization point object)
ranges::split_viewviews::split (C++20)	a view over the subranges obtained from splitting another view using a delimiter (class template) (range adaptor object)
views::counted (C++20)	creates a subrange from an iterator and a count (customization point object)
ranges::common_viewviews::common (C++20)	converts a view into a common_range (class template) (range adaptor object)
ranges::reverse_viewviews::reverse (C++20)	a view that iterates over the elements of another bidirectional view in reverse order (class template) (range adaptor object)
