## Detailed Description

template<typename Result_Type>
struct restinio::easy_parser::impl::producer_tag< Result_Type >

A special base class to be used with producers.

Every producer class should have the following content:

class some_producer_type
{
public:
using result_type = ... // some producer-specific type.
static constexpr entity_type_t entity_type = entity_type_t::producer;
expected_t<result_type, parse_error_t>
try_parse(source_t & from);
...
};
restinio::easy_parser::impl::entity_type_t
entity_type_t
A marker for distinguish different kind of entities in parser.
