Constants

const (

	// String Some default converter types for a nicer syntax
	String  string  = ""
	Bool    bool    = false
	Int     int     = 0
	Float32 float32 = 0
	Float64 float64 = 0
)

These flags define options for tag handling

Types

type Option

type Option struct {
	// setting this value to true will ignore copying zero values of all the fields, including bools, as well as a
	// struct having all it's fields set to their zero values respectively (see IsZero() in reflect/value.go)
	IgnoreEmpty bool
	DeepCopy    bool
	Converters  []TypeConverter
}

Option sets copy options

type TypeConverter

type TypeConverter struct {
	SrcType interface{}
	DstType interface{}
	Fn      func(src interface{}) (interface{}, error)
}
