As always, in FastAPI you can combine `def` and `async def` as needed.

    If you need a refresher about when to use which, check out the section _"In a hurry?"_ in the docs about [`async` and `await`](../async.md#in-a-hurry){.internal-link target=_blank}.

9. This *path operation function* is not returning dataclasses (although it could), but a list of dictionaries with internal data.

            plugins.forEach(p -> mergedPlugins.put(p.getPrefix(), p));
            metadata.setPlugins(new ArrayList<>(mergedPlugins.values()));

        // just carry-on as-is
        if (recessive.getVersioning() != null) {
            metadata.setVersioning(recessive.getVersioning());
        }
    }

        }

        artifacts.clear();

Możesz również zdefiniować to jako normalną funkcję zamiast `async def`:

/// note

Jeśli nie znasz różnicy, sprawdź [Async: *"In a hurry?"*](../async.md#in-a-hurry){.internal-link target=_blank}.

                        .listIterator(collectStepTrace.getPath().size());
                while (iter.hasPrevious()) {
                    DependencyNode curr = iter.previous();
                    indent += "  ";
                    trackingData.add(indent + curr + " (" + collectStepTrace.getContext() + ")");
                }
            }
        }

        if (trackingFile == null) {
            return;

    Se você precisar de uma atualização sobre quando usar qual, confira a seção _"Com pressa?"_ na documentação sobre [`async` e `await`](../async.md#in-a-hurry){.internal-link target=_blank}.

9. Esta *função de operação de rota* não está retornando dataclasses (embora pudesse), mas uma lista de dicionários com dados internos.

It doesn't matter. **FastAPI** will know what to do.

/// note

If you don't know, check the [Async: *"In a hurry?"*](../../async.md#in-a-hurry){.internal-link target=_blank} section about `async` and `await` in the docs.
