Signature:
func RandBytes(length int) []byte
Example:
package main
import (
"fmt"

func main() {
randBytes := random.RandBytes(4)
fmt.Println(randBytes)
}
# RandInt
Generate random int between min and max, may contain min, not max.
Signature:
func RandInt(min, max int) int

package main
import (
"fmt"
"github.com/duke-git/lancet/v2/random"
)
func main() {
rInt := random.RandInt(1, 10)
fmt.Println(rInt)
}
# RandInt
Generate random given length string.

func RandString(length int) string
Example:
package main
import (
"fmt"
"github.com/duke-git/lancet/v2/random"

func main() {
randStr := random.RandString(6)
fmt.Println(randStr)
}
# UUIdV4

func main() {
uuid, err := random.UUIdV4()
if err != nil {
return
}
fmt.Println(uuid)
}
