std::experimental::basic_string_view(3)

NAME
std::experimental::basic_string_view - std::experimental::basic_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 element of the
   sequence at position zero.
   A typical implementation holds only two members: a pointer to constant 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::basic_string_view<char>
   std::experimental::wstring_view std::experimental::basic_string_view<wchar_t>
   std::experimental::u16string_view std::experimental::basic_string_view<char16_t>
   std::experimental::u32string_view std::experimental::basic_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 LegacyRandomAccessIterator
   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 checking
                        (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 specialization)
   std::hash<std::experimental::u32string_view>
  Feature test macros
                        a value of at least 201411 indicates that
   __cpp_lib_experimental_string_view basic_string_view template is supported
                        (macro constant)
