	ErrNotAFn                    = errors.New("value is not a function")

Types

type Mapper

type Mapper struct {
	// contains filtered or unexported fields
}

Mapper maps struct values.

func New

func New() *Mapper

New returns new Mapper.

func (*Mapper) Map

func (m *Mapper) Map(from, to interface{}) error

Map maps two structs or two slices of structs.

func (*Mapper) Set

func (m *Mapper) Set(converter interface{}) error

Set sets converter function. Converter function must be in one of two forms:

func(in int) string
func(in string) (int, error)

Set will make the Mapper use the converter function to map in-type to out-type every time the Mapper comes across one.
