## Detailed Description

template<typename Scalar, typename Tag>
class restinio::utils::tagged_scalar_t< Scalar, Tag >

Helper template for defining tagged scalar types.

Usage example:

struct max_parallel_connections_tag {};
using max_parallel_connections_t = tagged_scalar_t<
std::size_t, max_parallel_connections_tag >;
struct max_active_accepts_tag {};
using max_active_accepts_t = tagged_scalar_t<
std::size_t, max_active_accepts_tag >;
class limiter_t
{
public:
limiter_t(
max_parallel_connections_t parallel_connections,
max_active_accepts_t active_accepts);
...
};
