/// tip | Tipp

Die Syntax `{"name", "description"}` erzeugt ein `set` mit diesen zwei Werten.

Äquivalent zu `set(["name", "description"])`.

///

#### `list`en statt `set`s verwenden { #using-lists-instead-of-sets }

Wenn Sie vergessen, ein `set` zu verwenden, und stattdessen eine `list`e oder ein `tuple` übergeben, wird FastAPI die dennoch in ein `set` konvertieren, und es wird korrekt funktionieren:

		c.addToBucket(ent)
		return false
	}

	// Add new item
	ent := c.evictList.PushFrontExpirable(key, value, now.Add(c.ttl))
	c.items[key] = ent
	c.addToBucket(ent) // adds the entry to the appropriate bucket and sets entry.expireBucket

	evict := c.size > 0 && c.evictList.Length() > c.size
	// Verify size not exceeded
	if evict {
		c.removeOldest()
	}
	return evict
}

Синтаксис `{"name", "description"}` создаёт `set` с этими двумя значениями.

Это эквивалентно `set(["name", "description"])`.

///

#### Использование `list` вместо `set` { #using-lists-instead-of-sets }

Если вы забыли использовать `set` и применили `list` или `tuple`, FastAPI всё равно преобразует это в `set`, и всё будет работать корректно:
