Вам редко нужно будет возвращаться к документации.

Вот как ваш редактор может вам помочь:

* в [Visual Studio Code](https://code.visualstudio.com/):

These functions are there (instead of just using the classes directly) so that your editor doesn't mark errors about their types.

That way you can use your normal editor and coding tools without having to add custom configurations to disregard those errors.

    // System.identityHashCode, which means the assignment of keys to segments is nondeterministic,
    // so more than (maximumSize / #segments) keys could get assigned to the same segment, which
    // would cause one to be evicted.

Il est **FORTEMENT encouragé** que vous écriviez ou copiez le code, l'éditiez et l'exécutiez localement.

L'utiliser dans votre éditeur est ce qui vous montre vraiment les avantages de FastAPI, en voyant le peu de code que vous avez à écrire, toutes les vérifications de type, l'autocomplétion, etc.

//     it defaults to defaultTTL.

// This function defines an onEvicted callback that is invoked when a cache entry is evicted.
// The callback ensures that if the evicted value (v) is not nil, its Close method is called asynchronously

你将能进行代码补全，这是在之前你可能曾认为不可能的事。例如，在来自请求 JSON 体（可能是嵌套的）中的键 `price`。

Y genera esquemas OpenAPI.

Así es como funciona en Flask, Starlette, Responder, etc.

Pero luego, tenemos otra vez el problema de tener una micro-sintaxis, dentro de un string de Python (un gran YAML).

El editor no puede ayudar mucho con eso. Y si modificamos parámetros o esquemas de Marshmallow y olvidamos también modificar ese docstring YAML, el esquema generado estaría obsoleto.
