∀ {α : Type u} [inst : PseudoMetricSpace α] {s t : Set α},
s.Nonempty → t.Nonempty → Bornology.IsBounded s → Bornology.IsBounded t → Metric.hausdorffEDist s t ≠ ⊤Alias of Metric.hausdorffEDist_ne_top_of_nonempty_of_bounded.
If two sets are nonempty and bounded in a metric space, they are at finite Hausdorff
edistance.
