rclcpp::detail::sub_info_shape_ref< M, D, bool > Struct Template Reference

Detailed Description

template<typename M, typename D, bool = sub_callable_with2<D, const M&, const ::rclcpp::MessageInfo&>::value>
struct rclcpp::detail::sub_info_shape_ref< M, D, bool >

Issue 2036 — the upstream two-argument shapes: the message in one of the four forms above, then const rclcpp::MessageInfo&. The values are the one-argument shape's, so subscription_heap_copy<M, Shape> serves both. Detected in the same order, for the same reason (a generic lambda is instantiated with a smart pointer only when const M& failed).
