Following code.
func fieldsTest(target interface{}) ([]field, error) {
s := reflect.ValueOf(target)
s = s.Elem()
targetType := s.Type()
for i := 0; i < s.NumField(); i++ {
f := s.Field(i)
structField := targetType.Field(i)
...
}
If the target interface is a struct, the return value of f are the same as structField?
Type.Field()
returns a value of type reflect.StructField
, and Value.Field()
returns a value of type reflect.Value
. So they cannot be the same.
Type.Field()
returns a value describing the field's type, regardless of any actual struct value. Value.Field()
returns a reflect.Value
that wraps the value of a field of a struct value.
