## Struct template trivial_value_traits

boost::intrusive::trivial_value_traits

## Synopsis

    // In header: <boost/intrusive/trivial_value_traits.hpp>

    template<typename NodeTraits, link_mode_type LinkMode = normal_link>
    struct trivial_value_traits {
      // types
      typedef NodeTraits                  node_traits;
      typedef node_traits::node_ptr       node_ptr;
      typedef node_traits::const_node_ptr const_node_ptr;
      typedef node_traits::node           value_type;
      typedef node_ptr                    pointer;
      typedef const_node_ptr              const_pointer;

      // public static functions
      static node_ptr to_node_ptr(value_type &);
      static const_node_ptr to_node_ptr(const value_type &);
      static const pointer & to_value_ptr(const node_ptr &);
      static const const_pointer & to_value_ptr(const const_node_ptr &);

## Description

This value traits template is used to create value traits from user defined node traits where value_traits::value_type and node_traits::node should be equal

### `trivial_value_traits` public static functions

1.     static node_ptr to_node_ptr(value_type & value);

2.     static const_node_ptr to_node_ptr(const value_type & value);

3.     static const pointer & to_value_ptr(const node_ptr & n);

4.     static const const_pointer & to_value_ptr(const const_node_ptr & n);
