Filter.Tendsto.liminf_eq

∀ {α : Type u_2} {β : Type u_3} [inst : ConditionallyCompleteLinearOrder α] [inst_1 : TopologicalSpace α]
  [OrderTopology α] {f : Filter β} {u : β → α} {a : α} [f.NeBot], Filter.Tendsto u f (nhds a) → Filter.liminf u f = a

If a function has a limit, then its liminf coincides with its limit.
