std::experi...string_view(3) C++ Standard Libary std::experi...string_view(3) NAME std::experimental::basic_string_view - std::experimental::ba- sic_string_view Synopsis Defined in header <experimental/string_view> template< class CharT, (library fundamentals TS) class Traits = std::char_traits<CharT> > class basic_string_view; The class template basic_string_view describes an object that can refer to a constant contiguous sequence of char-like objects with the first el- ement of the sequence at position zero. A typical implementation holds only two members: a pointer to con- stant CharT and a size. Several typedefs for common character types are provided: Defined in header <experimental/string_view> Type Definition std::experimental::string_view std::experimental::ba- sic_string_view<char> std::experimental::wstring_view std::experimental::ba- sic_string_view<wchar_t> std::experimental::u16string_view std::experimental::ba- sic_string_view<char16_t> std::experimental::u32string_view std::experimental::ba- sic_string_view<char32_t> Template parameters CharT - character type Traits - traits class specifying the operations on the character type Member types Member type Definition traits_type Traits value_type CharT pointer CharT* const_pointer const CharT* reference CharT& const_reference const CharT& const_iterator implementation-defined LegacyRandomAccessIt- erator iterator const_iterator reverse_iterator const_reverse_iterator const_reverse_iterator std::reverse_iterator<const_iterator> size_type std::size_t difference_type std::ptrdiff_t Note: iterator and const_iterator are the same type because string views are views into constant character sequences. Member functions constructor constructs a basic_string_view (public member function) operator= assigns a view (public member function) Iterators begin returns an iterator to the beginning cbegin (public member function) end returns an iterator to the end cend (public member function) rbegin returns a reverse iterator to the beginning crbegin (public member function) rend returns a reverse iterator to the end crend (public member function) Element access operator[] access specified character (public member function) at access specified character with bounds check- ing (public member function) front accesses the first character (public member function) back accesses the last character (public member function) data returns a pointer to the first character of a view (public member function) Capacity size returns the number of characters length (public member function) max_size returns the maximum number of characters (public member function) empty checks whether the view is empty (public member function) Modifiers remove_prefix Shrinks the view by moving its start forward (public member function) remove_suffix Shrinks the view by moving its end backward (public member function) swap swaps the contents (public member function) Operations to_string creates a string from the view operator basic_string (public member function) copy copies characters (public member function) substr returns a substring (public member function) compare compares two views (public member function) find find characters in the view (public member function) rfind find the last occurrence of a substring (public member function) find_first_of find first occurrence of characters (public member function) find_last_of find last occurrence of characters (public member function) find_first_not_of find first absence of characters (public member function) find_last_not_of find last absence of characters (public member function) Constants npos special value. The exact meaning depends on the context [static] (public static member constant) Non-member functions operator== operator!= operator< lexicographically compares two views operator> (function template) operator<= operator>= Input/output operator<< performs stream output on views (function template) Helper classes std::hash<std::experimental::string_view> std::hash<std::experimental::wstring_view> hash support for views std::hash<std::experimental::u16string_view> (class template spe- cialization) std::hash<std::experimental::u32string_view> Feature test macros a value of at least 201411 indi- cates that __cpp_lib_experimental_string_view basic_string_view template is supported (macro constant) http://cppreference.com 2022.07.31 std::experi...string_view(3)
