Dependency'ler de **FastAPI** tarafından çağrılacağı için (tıpkı *path operation function*'larınız gibi), fonksiyonları tanımlarken aynı kurallar geçerlidir.

`async def` ya da normal `def` kullanabilirsiniz.

Ayrıca normal `def` *path operation function*'ları içinde `async def` dependency tanımlayabilir veya `async def` *path operation function*'ları içinde `def` dependency kullanabilirsiniz vb.

  /**
   * A skeleton implementation of a descending multiset view. Normally, {@link
   * #descendingMultiset()} will not reflect any changes you make to the behavior of methods such as
   * {@link #add(Object)} or {@link #pollFirstEntry}. This skeleton implementation correctly

It has all the information about the *path operation* and is used to generate the automatic documentation.

It includes the `tags`, `parameters`, `requestBody`, `responses`, etc.

This *path operation*-specific OpenAPI schema is normally generated automatically by **FastAPI**, but you can also extend it.

/// tip

This is a low level extension point.

Como eso sucederá del lado de Rust, el rendimiento será mucho mejor que si se hiciera con Python normal y la clase `JSONResponse`.

Al usar un `response_model` o tipo de retorno, FastAPI no usará el `jsonable_encoder` para convertir los datos (lo cual sería más lento) ni la clase `JSONResponse`.

# Security { #security }

There are many ways to handle security, authentication and authorization.

And it normally is a complex and "difficult" topic.

In many frameworks and systems just handling security and authentication takes a big amount of effort and code (in many cases it can be 50% or more of all the code written).
