map3<C, D, E> method
Change the return type of this IOEither based on its value of type R
, the
value of type C
of a second IOEither, and the value of type D
of a third IOEither.
Implementation
@override
IOEither<L, E> map3<C, D, E>(covariant IOEither<L, C> m1,
covariant IOEither<L, D> m2, E Function(R b, C c, D d) f) =>
flatMap((b) => m1.flatMap((c) => m2.map((d) => f(b, c, d))));
