### BOOST_FUSION_ADAPT_STRUCT

##### Description

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

##### Synopsis

    BOOST_FUSION_ADAPT_STRUCT(
        struct_name,
        member_name0,
        member_name1,
        member_name2,
        ...
        )

    // Without BOOST_PP_VARIADICS support :
    BOOST_FUSION_ADAPT_STRUCT(
        struct_name,
        (member_type0, member_name0)
        (member_type1, member_name1)
        (auto, member_name2)
        ...
        )

##### Semantics

The above macro generates the necessary code to adapt `struct_name` as a model of Random Access Sequence.

The sequence of `member_nameN,` arguments or `(member_typeN, member_nameN)` pairs declares the type and names of each of the struct members that are part of the sequence.

When member_typeN is omitted or set to auto, the type is infered with Boost.TypeOf.

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

##### Example: BOOST_FUSION_ADAPT_STRUCT

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

    // demo::employee is now a Fusion sequence
    BOOST_FUSION_ADAPT_STRUCT(
        demo::employee,
        name,
        age)

    // Without BOOST_PP_VARIADICS support :
    BOOST_FUSION_ADAPT_STRUCT(
        demo::employee,
        (auto, name)
        (auto, age)
    )
