// PodFailurePolicyRule describes how a pod failure is handled when the requirements are met.
// One of onExitCodes and onPodConditions, but not both, can be used in each rule.
message PodFailurePolicyRule {
  // Specifies the action taken on a pod failure when the requirements are satisfied.
  // Possible values are:

Python selbst macht nichts mit `Annotated`. Für Editoren und andere Tools ist der Typ immer noch `str`.

Aber Sie können `Annotated` nutzen, um **FastAPI** mit Metadaten zu versorgen, die ihm sagen, wie sich ihre Anwendung verhalten soll.

Wichtig ist, dass **der erste *Typ-Parameter***, den Sie `Annotated` übergeben, der **tatsächliche Typ** ist. Der Rest sind Metadaten für andere Tools.

FastAPI is smart enough (actually, Pydantic is smart enough) to realize that, even though `description`, `tax`, and `tags` have the same values as the defaults, they were set explicitly (instead of taken from the defaults).

So, they will be included in the JSON response.

!!! tip
    Notice that the default values can be anything, not only `None`.

    They can be a list (`[]`), a `float` of `10.5`, etc.

You can learn how to use them and how they are integrated into **FastAPI** later in the **Advanced User Guide**.

## Recap

With what you have seen up to now, you can set up a secure **FastAPI** application using standards like OAuth2 and JWT.

In almost any framework handling the security becomes a rather complex subject quite quickly.

address space. This comment explains the operation of cgo.

Cgo reads a set of Go source files and looks for statements saying
import "C". If the import has a doc comment, that comment is
taken as literal C code to be used as a preamble to any C code
generated by cgo. A typical preamble #includes necessary definitions:

	// #include <stdio.h>
	import "C"
