Functions

func Unzip2 

func Unzip2[T1, T2 any](o Result[tuple.Tuple2[T1, T2]]) (Result[T1], Result[T2])

Unzip2 converts an optional of 2-tuple to optionals of each elements.

Example 
package main

import (
	"fmt"

	"github.com/shogo82148/hi/result"
	"github.com/shogo82148/hi/tuple"
)

func main() {
	ret := result.OK(tuple.New2(1, "one"))
	r1, r2 := result.Unzip2(ret)
	fmt.Println(r1.Get())
