Detailed Description

template<class... Fs>
struct parcel::Overload< Fs >

Lambda-overload set helper for parcel::visit.

Standard CTAD trick that turns a brace-enclosed list of lambdas into one callable whose operator() is overloaded across them. Pair with parcel::visit over a UnionCell to dispatch on the active alternative.

parcel::visit(parcel::Overload{
    [](std::int32_t i) { ... },
    [](std::string const& s) { ... },
}, my_union);
