Detailed Description

template<class I, class M>
struct duds::data::LargeIntWrapper< I, M >

Wraps an integer to allow the Boost multiprecision library to provide insertion and extraction operators, and to provide Boost serialization support that will produce the same result, while using either a native integer type or a Boost multiprecision type.

This is intended to allow the use of gcc's __int128 type on 64-bit targets and boost::multiprecision::int128_t on 32-bit targets, while allowing the integer in serialized form to be exchanged between the targets. For larger integers, it makes more sense to use something like Boost multiprecision on all targets.

Template Parameters
IThe underlying integer type used for storage.
MThe Boost multiprecision type used for stream I/O. This parameter may be the same as I.
