## Class index_view

boost::histogram::indexed_range::accessor::index_view — Array-like view into the current multi-dimensional index.

## Synopsis

    // In header: <boost/histogram/indexed.hpp>

    // Array-like view into the current multi-dimensional index.

    class index_view {
    public:
      // types
      typedef unspecified              const_iterator;
      typedef const axis::index_type & const_reference;

      // public member functions
      const_iterator begin() const noexcept;
      const_iterator end() const noexcept;
      std::size_t size() const noexcept;
      const_reference operator[](unsigned) const noexcept;
      const_reference at(unsigned) const;
    };
