Валидация также применима к значениям типа `float`.

     * - A multi-module project containing a module which is a plugin and another module which depends on it.
     * - Just the plugin is being built with the -f <pom> flag.
     * - Because of inter-module dependency collection, all projects in the multi-module project are collected.
     * - The plugin is not yet installed in a repository.

// errInconsistentDisk - inconsistent disk found.
var errInconsistentDisk = StorageErr("inconsistent drive found")

// errUnsupporteDisk - when disk does not support O_DIRECT flag.
var errUnsupportedDisk = StorageErr("drive does not support O_DIRECT")

// errDiskFull - cannot create volume or files when disk is full.
var errDiskFull = StorageErr("drive path full")

Параметры функции будут распознаны следующим образом:

* Если параметр также объявлен в **пути**, он будет использоваться как параметр пути.
* Если параметр имеет **скалярный тип** (например, `int`, `float`, `str`, `bool` и т. п.), он будет интерпретирован как параметр **запроса**.
* Если параметр объявлен как тип **модели Pydantic**, он будет интерпретирован как **тело** запроса.

* `description: Union[str, None] = None` (oder `str | None = None` in Python 3.10) hat einen Defaultwert `None`.
* `tax: float = 10.5` hat einen Defaultwert `10.5`.
* `tags: List[str] = []` hat eine leere Liste als Defaultwert: `[]`.

Aber Sie möchten diese vielleicht vom Resultat ausschließen, wenn Sie gar nicht gesetzt wurden.
