Although in FastAPI it's optional, and is used mainly to set headers, cookies, and alternative status codes.

I discovered Molten in the first stages of building **FastAPI**. And it has quite similar ideas:

* Based on Python type hints.
* Validation and documentation from these types.
* Dependency Injection system.

與使用 FastAPI 建置相同的開銷。在許多情況下，這種資料驗證和序列化是應用程式中編寫最大量的程式碼。
L33:    * 因此透過使用 FastAPI，你可以節省開發時間、錯誤與程式碼數量，並且相比不使用 FastAPI 你很大可能會獲得相同或更好的效能（因為那樣你必須在程式碼中實現所有相同的功能）。
L34:    * 如果你要與 FastAPI 比較，請將其與能夠提供資料驗證、序列化和文件的網頁應用程式框架（或工具集）進行比較，例如 Flask-apispec、NestJS、Molten 等框架。

 * iterators that don't support {@code remove()}. Otherwise, all optional operations are supported.
 * Null row keys, columns keys, and values are not supported.
 *
 * <p>Lookups by row key are often faster than lookups by column key, because the data is stored in
 * a {@code Map<R, Map<C, V>>}. A method call like {@code column(columnKey).get(rowKey)} still runs

# An export free of arguments in a Makefile places all variables in the Makefile into the
# environment. This behavior may be surprising to many that use shell often, which simply
# displays the existing environment

     * For example, if concentration=2.0, the following takes the square root of
     * the uniformly-distributed random integer, then truncates any fractional
     * part, so higher integers would appear (in this case linearly) more often
     * than lower ones.

    return (int) Math.pow(a, 1.0 / concentration);
  }

  @AfterExperiment
  void tearDown() {
    double req = requests.get();
    double hit = req - misses.get();

// so there is no risk of polluting the entire cache with data accessed once.
// Another goal of DirectIO is to minimize the mutation of data by the kernel
// before issuing IO to underlying devices. ZFS users often enable features like
// compression and checksumming which currently necessitates mutating data in
// the kernel.
//
// DirectIO semantics for a filesystem like ZFS would be quite different than

**FastAPI**'ı geliştirmenin ilk aşamalarında Molten'ı keşfettim. Pek çok ortak fikrimiz vardı:

* Python'daki tip belirteçlerini baz alıyordu.
* Bunlara bağlı olarak veri doğrulaması ve dökümantasyon sağlıyordu.

    Embora no FastAPI seja opcional, é utilizado principalmente para configurar cabeçalhos, cookies e códigos de status alternativos.

Eu descobri Molten nos primeiros estágios da construção do **FastAPI**. E ele tem umas idéias bem similares:

* Baseado em _type hints_ Python.
* Validação e documentação desses tipos.
* Sistema de injeção de dependência.

    * 因此，通过使用 FastAPI 意味着您可以节省开发时间，减少编码错误，用更少的编码实现其功能，并且相比不使用 FastAPI 您很大可能会获得相同或更好的性能（因为那样您必须在代码中实现所有相同的功能）。
