Functions

func Copy

func Copy(dest, src interface{}) error

Copy 浅拷贝

@param dest (1) 如果为nil,将返回error

(2) 必须是指针类型

@param src (1) 如果为nil,将返回error

(2) 指针类型 || 结构体实例

e.g.

b := &bean{
	Id: 666,
}
src := map[string]interface{}{
	"b":   false,
	"tmp": b,
}
dest := make(map[string]interface{})
if err := copyKit.Copy(&dest, src); err != nil {
	panic(err)
}

// {"b":false,"tmp":{"Id":666}} <nil>
fmt.Println(jsonKit.MarshalToString(src, jsonKit.WithApi(jsoniter.ConfigCompatibleWithStandardLibrary)))
// {"b":false,"tmp":{"Id":666}} <nil>
fmt.Println(jsonKit.MarshalToString(dest, jsonKit.WithApi(jsoniter.ConfigCompatibleWithStandardLibrary)))

src["b"] = true
b.Id = 777

// {"b":true,"tmp":{"Id":777}} <nil>
fmt.Println(jsonKit.MarshalToString(src, jsonKit.WithApi(jsoniter.ConfigCompatibleWithStandardLibrary)))
// {"b":false,"tmp":{"Id":777}} <nil>
fmt.Println(jsonKit.MarshalToString(dest, jsonKit.WithApi(jsoniter.ConfigCompatibleWithStandardLibrary)))

func DeepCopy

func DeepCopy[T any](src T) T

DeepCopy 深拷贝(通过lancet).

PS: 不支持未导出的字段.

@param src 可以为nil(此时将返回nil)

func DeepCopy1

func DeepCopy1[T any](src T) (dest T, err error)

DeepCopy1 深拷贝(通过GoFrame中的 gutil).

PS: (1) 不支持未导出的字段 unable to copy unexported fields in a struct (lowercase field names) (2) 不使用 github.com/mohae/deepcopy: 虽然效果一样,但不推荐使用(star少; 最后更新时间2017) (3) 不使用 github.com/jinzhu/copier: 深拷贝有bug,详见"Golang.wps"

@param src (1) 可以为nil(此时将返回: nil, nil)

(2) 必须是: 结构体实例的指针 || map实例 || slice实例
