CatsMonadToMonoid

class CatsMonadToMonoid[F[_], A] extends CatsMonadToSemigroup[F, A] with Monoid[F[A]]

Given that A has a cats.Semigroup implementation, this builds a Semigroup[F[A]] instance for any F[_] data type that implements cats.Monad.

Used for both Task and monix.eval.Coeval.

NOTE: nothing in this implementation is specific to Monix or to cats-effect, but these instances are not provided by default by Cats for any monad, probably because they aren't useful for every monad.
