Metric.ediam_le_of_forall_dist_le
∀ {α : Type u} {s : Set α} [inst : PseudoMetricSpace α] {C : ℝ},
(∀ x ∈ s, ∀ y ∈ s, dist x y ≤ C) → Metric.ediam s ≤ ENNReal.ofReal CIf the distance between any two points in a set is bounded by some constant C,
then ENNReal.ofReal C bounds the emetric diameter of this set.
