Types

type Result

type Result[T, E any] struct {
	// contains filtered or unexported fields
}

func Error

func Error[T, E any](err E) Result[T, E]

func Map

func Map[T, E, U any](r Result[T, E], op func(T) U) Result[U, E]

Example

package main

import (
	"fmt"

	"codeberg.org/FedericoSchonborn/go-sandbox/result"
	"codeberg.org/FedericoSchonborn/go-sandbox/result/strconv"
)

func main() {
	value := result.Map(strconv.Atoi("2"), func(i int) int {
		return i * 2
	})
	fmt.Println(value)

}

Output:

Ok(4)

func Ok

func Ok[T, E any](value T) Result[T, E]

func Try

func Try[T any, E error](value T, err E) Result[T, E]

Example

package main

import (
	"fmt"
	"time"

	"codeberg.org/FedericoSchonborn/go-sandbox/result"
)

func main() {
	value := result.Try(time.LoadLocation("Local"))
	fmt.Println(value)

}

Output:

Ok(Local)
