As Pydantic will serialize it in the **Rust** side, you will get much higher **performance** than if you don't declare a return type.

### Non-async *path operation functions* { #non-async-path-operation-functions }

You can also use regular `def` functions (without `async`), and use `yield` the same way.

FastAPI will make sure it's run correctly so that it doesn't block the event loop.

This is a slower operation that does not use replication queues and is designed to walk the namespace and replicate objects one at a time so as not to impede server load. Ideally, resync should not be initiated for multiple buckets simultaneously - progress of the syncing can be monitored by looking at `mc replicate resync status alias/bucket --remote-bucket <arn>`. In the event that resync operation failed to replicate some versions, they would be picked up...

 *   <li>The {@code copyOf} methods will sometimes recognize that the actual copy operation is
 *       unnecessary; for example, {@code copyOf(copyOf(anArrayList))} should copy the data only
 *       once. This reduces the expense of habitually making defensive copies at API boundaries.
 *       However, the precise conditions for skipping the copy operation are undefined.

`Query`, `Path` ve `Body` ile *path operation function* parametrelerinde ek doğrulama ve metadata tanımlayabildiğiniz gibi, Pydantic modellerinin içinde de Pydantic'in `Field`'ını kullanarak doğrulama ve metadata tanımlayabilirsiniz.

## `Field`'ı import edin { #import-field }

### Async Olmayan Path Operation Fonksiyonları { #non-async-path-operation-functions }

Normal `def` fonksiyonlarını (yani `async` olmadan) da kullanabilir ve aynı şekilde `yield` kullanabilirsiniz.

FastAPI, event loop'u bloke etmeyecek şekilde doğru biçimde çalışmasını sağlar.

`APIRouter` に追加済みなので、各 *path operation* に `/items` の prefix や `tags=["items"]` を付けていません。

しかし、特定の *path operation* に適用される _追加の_ `tags` や、その *path operation* 固有の追加の `responses` を加えることはできます:

{* ../../docs_src/bigger_applications/app_an_py310/routers/items.py hl[30:31] title["app/routers/items.py"] *}

/// tip | 豆知識

この最後の *path operation* は、`["items", "custom"]` のタグの組み合わせを持ちます。
