Types

type Either 

type Either[E, A any] either

Either defines a data structure that logically holds either an E or an A. The flag discriminates the cases

Example (Creation)

Code: 

{
	// Build an Either
	leftValue := Left[string](fmt.Errorf("some error"))
	rightValue := Right[error]("value")

	// Build from a value
	fromNillable := FromNillable[string](fmt.Errorf("value was nil"))
	leftFromNil := fromNillable(nil)
	value := "value"
	rightFromPointer := fromNillable(&value)

	// some predicate
	isEven := func(num int) bool {
		return num%2 == 0
	}
	fromEven := FromPredicate(isEven, errors.OnSome[int]("%d is an odd number"))
	leftFromPred := fromEven(3)
	rightFromPred := fromEven(4)

	fmt.Println(leftValue)
	fmt.Println(rightValue)
	fmt.Println(leftFromNil)
	fmt.Println(IsRight(rightFromPointer))
	fmt.Println(leftFromPred)
	fmt.Println(rightFromPred)

	// Output:
	// Left[*errors.errorString](some error)
	// Right[string](value)
	// Left[*errors.errorString](value was nil)
	// true
	// Left[*errors.errorString](3 is an odd number)
	// Right[int](4)

}

Output:

Left[*errors.errorString](some error)
Right[string](value)
Left[*errors.errorString](value was nil)
true
Left[*errors.errorString](3 is an odd number)
Right[int](4)
Example (Extraction)

Code: 

{
	leftValue := Left[int](fmt.Errorf("Division by Zero!"))
	rightValue := Right[error](10)

	// Convert Either[E, A] to A with a default value
	leftWithDefault := GetOrElse(F.Constant1[error](0))(leftValue)   // 0
	rightWithDefault := GetOrElse(F.Constant1[error](0))(rightValue) // 10

	// Apply a different function on Left(...)/Right(...)
	doubleOrZero := Fold(F.Constant1[error](0), N.Mul(2)) // func(Either[error, int]) int
	doubleFromLeft := doubleOrZero(leftValue)             // 0
	doubleFromRight := doubleOrZero(rightValue)           // 20

	// Pro-tip: Fold is short for the following:
	doubleOrZeroBis := F.Flow2(
		Map[error](N.Mul(2)),
		GetOrElse(F.Constant1[error](0)),
	)
	doubleFromLeftBis := doubleOrZeroBis(leftValue)   // 0
	doubleFromRightBis := doubleOrZeroBis(rightValue) // 20

	fmt.Println(leftValue)
	fmt.Println(rightValue)
	fmt.Println(leftWithDefault)
	fmt.Println(rightWithDefault)
	fmt.Println(doubleFromLeft)
	fmt.Println(doubleFromRight)
	fmt.Println(doubleFromLeftBis)
	fmt.Println(doubleFromRightBis)

	// Output:
	// Left[*errors.errorString](Division by Zero!)
	// Right[int](10)
	// 0
	// 10
	// 0
	// 20
	// 0
	// 20
}

Output:

Left[*errors.errorString](Division by Zero!)
