Pointer Function Examples

DefaultIfNil Example - Return Default Value if Pointer is Nil

package main

import (
	"fmt"

	"github.com/kashifkhan0771/utils/pointers"
)

func main() {
	// Example of DefaultIfNil for a string pointer
	var str *string
	defaultStr := "Default String"
	result := pointers.DefaultIfNil(str, defaultStr)
	fmt.Println(result)
}

Output:

Default String

NullableBool Example - Get Value from Bool Pointer

package main

import (
	"fmt"

	"github.com/kashifkhan0771/utils/pointers"
)

func main() {
	// Example of NullableBool for a bool pointer
	var flag *bool
	result := pointers.NullableBool(flag)
	fmt.Println(result)
}

Output:

false

NullableTime Example - Get Value from Time Pointer

package main

import (
	"fmt"
	"time"

	"github.com/kashifkhan0771/utils/pointers"
)

func main() {
	// Example of NullableTime for a time.Time pointer
	var t *time.Time
	result := pointers.NullableTime(t)
	fmt.Println(result)
}

Output:

0001-01-01 00:00:00 +0000 UTC

NullableInt Example - Get Value from Int Pointer

package main

import (
	"fmt"

	"github.com/kashifkhan0771/utils/pointers"
)

func main() {
	// Example of NullableInt for an int pointer
	var num *int
	result := pointers.NullableInt(num)
	fmt.Println(result)
}

Output:

0

NullableString Example - Get Value from String Pointer

package main

import (
	"fmt"

	"github.com/kashifkhan0771/utils/pointers"
)

func main() {
	// Example of NullableString for a string pointer
	var str *string
	result := pointers.NullableString(str)
	fmt.Println(result)  // Output: ""
}

Output:

""
