Functions

func Clone

func Clone(tgt any, src any, opts ...Option) error

Clone 将值从 src 克隆到 tgt

Types

type Cloner

type Cloner func(labels []string, tgtVal reflect.Value, srcVal reflect.Value) (bool, error)

Cloner is a clone hook.

type ClonerFrom

type ClonerFrom interface {
	// CloneFrom 如果返回一个错误，则终止clone, 如果bool返回true，则代表当前克隆结束，如果返回false，则代表没有克隆，需要继续克隆。
	CloneFrom(src any) (bool, error)
}

ClonerFrom 自定义克隆方法，从源克隆到自己

type ClonerTo

type ClonerTo interface {
	// CloneTo 如果返回一个错误，则终止clone, 如果bool返回true，则代表当前克隆结束，如果返回false，则代表没有克隆结束，需要继续克隆。
	CloneTo(tgt any) (bool, error)
}

ClonerTo 自定义克隆方法，将自己克隆到目标

type Code int

type Error

type Error struct {
	Code       Code
	Labels     []string
	TargetType reflect.Type

	// contains filtered or unexported fields
}
