And then **FastAPI** will call that override instead of the original dependency.

/// tip

You can set a dependency override for a dependency used anywhere in your **FastAPI** application.

The default pkg-config tool may be changed by setting the PKG_CONFIG environment variable.

For security reasons, only a limited set of flags are allowed, notably -D, -U, -I, and -l.
To allow additional flags, set CGO_CFLAGS_ALLOW to a regular expression
matching the new flags. To disallow flags that would otherwise be allowed,
set CGO_CFLAGS_DISALLOW to a regular expression matching arguments
that must be disallowed. In both cases the regular expression must match

* `frozenset`:
    * В запросах и ответах обрабатывается так же, как и `set`:
        * В запросах будет прочитан список, исключены дубликаты и преобразован в `set`.
        * В ответах `set` будет преобразован в `list`.
        * В сгенерированной схеме будет указано, что значения `set` уникальны (с помощью JSON-схемы `uniqueItems`).
