Client Concepts

response_filter

Filter type used to setup responses before being passed to the handler

of malloy::client::controller::http_request (or https_request).

Requires:

• std::move_constructible
• f.body_for(h) -> std::variant<Ts...>
• std::visit([](auto& v){ decltype(v)::value_type r; f.setup_body(h, r); }, f.body_for(h)) (setup_body must be a visitor over the value_types of the response bodies returned by f.body_for(h))

http_callback

Callback type used to provide responses to http(s) requests. Takes another type that satisfies response_filter, referred to as Filter from now on.

Requires:

• std::move_constructible
• (malloy::http::response<Ts>&&) -> void where Filter::body_for(..) -> std::variant<Ts...>.
