Detailed Description

template<template< typename... > class Variant>
struct visit_helper< Variant >

Helper class which abstracts away variant's visit function.

std::variant and similar namespace::variant types which provide a namespace::visit() function are handled here automatically using argument-dependent lookup. Users can provide specializations for other variant-like classes, e.g. boost::variant and boost::apply_visitor.
