Struct kwap_msg::OptNumber

pub struct OptNumber(pub u32);

The Option number identifies which Option is being set (e.g. Content-Format has a Number of 12)

Because Option Numbers are only able to be computed in the context of other options, in order to get Option Numbers you must have a collection of Opts.

Then you can use the provided EnumerateOptNumbers iterator extension to enumerate over options with their numbers.
