Transform Results

Result transformation

of valid values with map

• Result.valid(1337).map(_ - 1295) ==== Valid(42)

• Result.invalid(1337).map((_: Int) + 42) ==== Invalid(1337)

of invalid values with invalidMap

• Result.valid(42).invalidMap((_: Int) + 1295) ==== Valid(42)

• Result.invalid(1295).invalidMap(_ + 42) ==== Invalid(1337)

of both values with bimap

• Result.valid(1337).bimap((_: Int) + 42, _ - 1295) ==== Valid(42)

• Result.invalid(1295).bimap(_ + 42, (_: Int) + 42) ==== Invalid(1337)

of valid values while discarding invalids with flatMap

• Result.valid(1337).flatMap(a ⇒ Result.valid(a - 1295)) ==== Valid(42)

• Result.invalid(1337).flatMap((a: Int) ⇒ Result.valid(42)) ==== Invalid(1337)

• Result.valid(42).flatMap(a ⇒ Result.invalid(a + 1295)) ==== Invalid(1337)

• Result.invalid(1337).flatMap((a: Int) ⇒ Result.invalid(a + 1295)) ==== Invalid(1337)

of invalid values with recover

• Result.valid(42).recover(identity) ==== Valid(42)

• Result.invalid(1337).recover(_ - 1295) ==== Valid(42)

of invalid values with recoverWith

• Result.valid(42).recoverWith(Function.const(Result.valid(1337))) ==== Valid(42)

• Result.invalid(1337).recoverWith(Function.const(Result.valid(42))) ==== Valid(42)

• Result.valid(42).recoverWith(Function.const(Result.invalid(1337))) ==== Valid(42)

• Result.invalid(42).recoverWith(Function.const(Result.invalid(1337))) ==== Invalid(1337)

of swapped values

• Result.valid(42).swapped(_.map(_ :+ 1337)) ==== Valid(NonEmptyVector.of(42))

• Result.invalid(42).swapped(_.map(_ :+ 1337)) ==== Invalids(NonEmptyVector.of(42, 1337))

swap exchanges valid and invalid

• Result.invalid(42).swap ==== Valid(NonEmptyVector(42))

• Result.valid(1337).swap ==== Invalid(1337)
