def Array.mapMonoM {m : Type u_1 → Type u_2} {α : Type u_1} [Monad m] (as : Array α) (f : α → m α) : m (Array α)

Monomorphic Array.mapM. The internal implementation uses pointer equality, and does not allocate a new array if the result of each f a is a pointer equal value a.

Equations

• as.mapMonoM f = Array.mapM f as

Equations

• as.mapMono f = (as.mapMonoM f).run
