示例1: deserializeStructInternal
// deserializeStructInternal is a helper function for deserializeStruct.
// It takes a gob decoder and struct field metadata, and then assigns the correct value to the specified struct field.
func deserializeStructInternal(dec *gob.Decoder, fi *fieldInfo, fieldName string, nameParts []string, slice, zeroValue bool, structHistory map[string]map[string]bool, v reflect.Value, t reflect.Type) error {
if len(fi.sliceIndex) > 0 {
v = v.FieldByIndex(fi.sliceIndex)
t = v.Type()
var sv reflect.Value
createNew := false
nameIdx := len(fi.sliceIndex)
