pub fn answers(op: &Operation, matches: &ArgMatches) -> AnswersExpand description
What the user answered at the gate, read off one operation’s ArgMatches:
the write confirmation, and every named gate the operation carries.
A read carries neither flag, so there is nothing to ask it.
A flag the command never declared reads as unanswered, which is the closed
answer: it holds the request back. That is what makes this safe to point at
a command this crate did not build — a verb of your own, or one built before
an Overlay named a new gate. Give your own command its flags with gates
and the two stay in step by construction.
