📖 Usage

package main

import (
    "fmt"
    "github.com/iqbalmind/go-deepcopy"
)

type Address struct {
    Street string
    City   string
}

type Person struct {
    Name    string
    Age     int
    Address *Address
}

func main() {
    original := Person{
        Name: "Dewi",
        Age:  28,
        Address: &Address{
            Street: "Jl. Braga No. 99",
            City:   "Bandung",
        },
    }

    cloned, _ := deepcopy.DeepCopy(original)
    clonedPerson := cloned.(Person)

    // Modify the cloned struct
    clonedPerson.Name = "Budi"
    clonedPerson.Address.Street = "Jl. Asia Afrika No. 45"

    fmt.Println("Original:", original.Name, original.Address.Street)
    fmt.Println("Cloned:", clonedPerson.Name, clonedPerson.Address.Street)
}
