Utilities that returns a pointer to the value.

go-pointer provides functions that is returned pointer to basic types in Go such as Int, Uint32 and String, and functions that returned a value referenced by the pointer, such as IntValue and StringValue. When your Go version is 1.18 or higher, it provides generic New, Value function too.

Rarely, when you need a slice of pointer to any basic types, you can use Slice-suffixed functions corresponded to the type.

import (
	"fmt"

	"github.com/lufia/go-pointer"
)

func main() {
	p := pointer.Int(10)
	fmt.Printf("p = %d\n", pointer.IntValue(p))

	for _, p := range pointer.StringSlice("hello", "world") {
		fmt.Printf("p = %s\n", pointer.StringValue(p))
	}

	// Go 1.18 or higher
	q := pointer.New(20)
	fmt.Printf("q = %d\n", pointer.Value(q))
	for _, p := range pointer.Slice(10, 20) {
		fmt.Printf("p = %d\n", pointer.Value(p))
	}
}
