Value:

    static_assert(::nros::format_of<M>::value == ::nros::linked_format(),                          \
                  "RFC-0088: this message type is not encoded in the format the linked "           \
                  "backend speaks: one image, one backend, one encoding. A bridge image "          \
                  "is the only place two formats legitimately meet, and it converts "              \
                  "explicitly.")

Assert that message type M is encoded in the format the linked backend speaks. Expanded at every typed entity-creation site — the C++ sibling of nros_node::format_check::assert_message_format.

A macro, not a function, so the failing static_assert reports the file and line of the create_publisher / create_subscription call rather than a line inside this header.
