Então, nós podemos utilizar este `checker` em um `Depends(checker)`, no lugar de `Depends(FixedContentQueryChecker)`, porque a dependência é a instância, `checker`, e não a própria classe.

E quando a dependência for resolvida, o **FastAPI** chamará este `checker` como:

```Python
checker(q="somequery")
```

    checkNotNull(input);

    try (OutputStream out = openStream()) {
      return ByteStreams.copy(input, out);
    }

Especificamente, para ver o Uvicorn, Starlette e FastAPI comparados entre si (entre diversas outras ferramentas).

Quanto mais simples o problema resolvido pela ferramenta, melhor será a performance. E a maioria das análises não testa funcionalidades adicionais que são oferecidas pela ferramenta.

A hierarquia é:

Especificamente, observa-se Uvicorn, Starlette e FastAPI comparados juntos (entre muitas outras ferramentas).

Quanto mais simples o problema resolvido pela ferramenta, melhor a performance que ela terá. E a maioria dos _benchmarks_ não testam as características adicionais fornecidas pela ferramenta.

A hierarquia segue assim:
