Function DecodeHookExec

decode_hooks.go:41–55

DecodeHookExec executes the given decode hook. This should be used since it'll naturally degrade to the older backwards compatible DecodeHookFunc that took reflect.Kind instead of reflect.Type.

(
	raw DecodeHookFunc,
	from reflect.Value, to reflect.Value)

// since it'll naturally degrade to the older backwards compatible DecodeHookFunc
// that took reflect.Kind instead of reflect.Type.
func DecodeHookExec(
	raw DecodeHookFunc,
	from reflect.Value, to reflect.Value) (interface{}, error) {

	switch f := typedDecodeHook(raw).(type) {
	case DecodeHookFuncType:
		return f(from.Type(), to.Type(), from.Interface())
	case DecodeHookFuncKind:
		return f(from.Kind(), to.Kind(), from.Interface())
	case DecodeHookFuncValue:
		return f(from, to)
	default:
		return nil, errors.New("invalid decode hook signature")
	}
}

// ComposeDecodeHookFunc creates a single DecodeHookFunc that
// automatically composes multiple DecodeHookFuncs.
