	Bool    bool    = false
	Int     int     = 0
	Float32 float32 = 0

type FieldNameMapping

type FieldNameMapping struct {
	SrcType interface{}

	Mapping map[string]string
}

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
	CaseSensitive bool
	DeepCopy      bool
	Converters    []TypeConverter
	// Custom field name mappings to copy values with different names in `fromValue` and `toValue` types.
	// Examples can be found at `TestCustomFieldName`.
	FieldNameMapping []FieldNameMapping
}

Option sets copy options
