### BOOST_FUSION_ADAPT_ASSOC_STRUCT

#### Description

BOOST_FUSION_ADAPT_ASSOC_STRUCT is a macro that can be used to generate all the necessary boilerplate to make an arbitrary struct into a model of Random Access Sequence and Associative Sequence.

#### Synopsis

    BOOST_FUSION_ADAPT_ASSOC_STRUCT(
        struct_name
        (member_type0, member_name0, key_type0)
        (member_type1, member_name1, key_type1)
        ...
        )

#### Semantics

The above macro generates the necessary code to adapt `struct_name` as a model of Random Access Sequence and Associative Sequence. The sequence of `(member_typeN, member_nameN, key_typeN)` triples declare the type, name and key type of each of the struct members that will be part of the sequence.

The macro should be used at global scope, and `struct_name` should be the fully namespace qualified name of the struct to be converted.

#### Header

    #include <boost/fusion/adapted/struct/adapt_assoc_struct.hpp>
    #include <boost/fusion/include/adapt_assoc_struct.hpp>

#### Example

    namespace demo
    {
        struct employee
        {
            std::string name;
            int age;
        };
    }

    namespace keys
    {
        struct name;
        struct age;
    }

    // demo::employee is now a Fusion sequence
    // It is also an associative sequence with
    // keys keys::name and keys::age present.
    BOOST_FUSION_ADAPT_ASSOC_STRUCT(
        demo::employee
        (std::string, name, keys::name)
        (int, age, keys::age))
