|

* Interface
|
||||
|
||||
- Результат `ValueOf` - всегда конкретный тип.
|
||||
|
||||
var w io.Writer
|
||||
t := reflect.TypeOf(w) // t == ???
|
||||
|
||||
var v interface{} = w // v == nil
|
||||
t = reflect.TypeOf(v) // t == ???
|
||||
|
||||
- Чтобы получить `reflect.Type` равный интерфейсу, нужно использовать промежуточный указатель.
|
||||
|
||||
var w io.Writer
|
||||
ptrT := reflect.TypeOf(&w) // ptrT == *io.Writer
|
||||
t := ptrT.Elem() // t == io.Writer
|
||||
|
||||
* Заключение
|
||||
|
||||
- `reflect` создаёт хрупкий код. Там, где была бы ошибка компилятора, возникает `panic` во время исполнения.
|
||||
- Поведение `reflect` кода нужно документировать отдельно, и оно не ясно из типов аргументов.
|
||||
- `reflect` работает медленнее, чем специализация под конкретный тип.
