# Classes as Dependencies

Before diving deeper into the **Dependency Injection** system, let's upgrade the previous example.

## A `dict` from the previous example

In the previous example, we were returning a `dict` from our dependency ("dependable"):

var globalOSMetrics osMetrics

func init() {
	// Inject metrics.
	ioutilx.OsOpenFile = OpenFile
	ioutilx.OpenFileDirectIO = OpenFileDirectIO
	ioutilx.OsOpen = Open
}

type osMetrics struct {
	// All fields must be accessed atomically and aligned.

        val versionsToIncubating = mutableMapOf<Version, MutableSet<IncubatingDescription>>()
        JavaParser().parse(sourceFile).getResult().get().run {
            solver.inject(this)
            findAllIncubating()
                .map { node -> toVersionIncubating(sourceFile, node) }
                .forEach { (version, incubating) ->

# Classes como Dependências

Antes de nos aprofundarmos no sistema de **Injeção de Dependência**, vamos melhorar o exemplo anterior.

## `dict` do exemplo anterior

No exemplo anterior, nós retornávamos um `dict` da nossa dependência ("injetável"):

//// tab | Python 3.10+

```Python hl_lines="9"
{!> ../../docs_src/dependencies/tutorial001_an_py310.py!}
```

`MINIO_ROOT_USER_FILE` and `MINIO_ROOT_PASSWORD_FILE` also support custom absolute paths, in case Docker secrets are mounted to custom locations or other tools are used to mount secrets into the container. For example, HashiCorp Vault injects secrets to `/vault/secrets`. With the custom names above, set the environment variables to

```
MINIO_ROOT_USER_FILE=/vault/secrets/my_access_key
MINIO_ROOT_PASSWORD_FILE=/vault/secrets/my_secret_key
```

### Wstrzykiwanie Zależności

FastAPI zawiera niezwykle łatwy w użyciu, ale niezwykle potężny system <abbr title='Po angielsku: Dependency Injection. Znane również jako "components", "resources", "services", "providers"'><strong>Wstrzykiwania Zależności</strong></abbr>.

* Nawet zależności mogą mieć zależności, tworząc hierarchię lub **"graf" zależności**.
