Submodule.coe_span_eq_self

∀ {R : Type u_1} {M : Type u_4} {S : Type u_7} [inst : Semiring R] [inst_1 : AddCommMonoid M] [inst_2 : Module R M]
  [inst_3 : SetLike S M] [AddSubmonoidClass S M] [SMulMemClass S R M] (s : S), ↑(Submodule.span R ↑s) = ↑s

A version of Submodule.span_eq for subobjects closed under addition and scalar multiplication and containing zero. In general, this should not be used directly, but can be used to quickly generate proofs for specific types of subobjects.
