Detailed Description

template<class Key, class Value>
struct cereal::MapItem< Key, Value >

A wrapper around a key and value for serializing data into maps.

This class just provides a grouping of keys and values into a struct for human readable archives. For example, XML archives will use this wrapper to write maps like so:

<mymap>
  <item0>
    <key>MyFirstKey</key>
    <value>MyFirstValue</value>
  </item0>
  <item1>
    <key>MySecondKey</key>
    <value>MySecondValue</value>
  </item1>
</mymap>
