View on Github →feat(algebra/order/monoid): Co/contravariant classes for with_bot
/with_top
(#13369)
Add the covariant_class (with_bot α) (with_bot α) (+) (≤)
and contravariant_class (with_bot α) (with_bot α) (+) (<)
instances, as well as the lemmas that covariant_class (with_bot α) (with_bot α) (+) (<)
and contravariant_class (with_bot α) (with_bot α) (+) (≤)
almost hold.
On the way, match the APIs for with_bot
/with_top
by adding missing lemmas.
