Module coap_numbers::signaling_option

Constants and functions for options in signaling CoAP messages (7.xx)

Like in the options module, numbers are expressed as u16 values. The applicability of options is not expressed here yet other than in the lookup, for it is unclear yet how that would be usable in practice. (A program is likely to branch on the signaling code before doing any option number evaluation).
