## Description of `xl.meta`

`xl.meta` is a new self describing backend format used by MinIO to support AWS S3 compatible versioning.
This file is the source of truth for each `version` at rest. `xl.meta` is a msgpack file serialized from a
well defined data structure. To understand `xl.meta` here are the few things to start with

`xl.meta` carries first 8 bytes an XL header which describes the current format and the format version,

@app.post("/items/")
async def create_item(item: Item, project_id: Annotated[int, Query(...)]): ...
```

## Return Type or Response Model

When possible, include a return type. It will be used to validate, filter, document, and serialize the response.

```python
from fastapi import FastAPI
from pydantic import BaseModel

app = FastAPI()


class Item(BaseModel):
    name: str
    description: str | None = None

  client_job->mutable_tasks()->insert(
      {0, absl::StrCat("localhost:", client_port)});
  server_def.set_job_name("localhost");
  auto serialized = server_def.SerializeAsString();
  TFE_ContextSetServerDef(ctx, 0, serialized.data(), serialized.size(), status);
  EXPECT_EQ(TF_GetCode(status), TF_OK) << TF_Message(status);

  EXPECT_EQ(TF_GetCode(status), TF_OK) << TF_Message(status);

/// warning | Uyarı

Yukarıdaki örnekte olduğu gibi bir `Response`'u doğrudan döndürdüğünüzde, response aynen olduğu gibi döndürülür.

Bir model ile serialize edilmez, vb.

İçinde olmasını istediğiniz veriyi taşıdığından emin olun ve değerlerin geçerli JSON olduğundan emin olun (eğer `JSONResponse` kullanıyorsanız).

* `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`.

* `frozenset`:
    * Em requisições e respostas, será tratado da mesma forma que um `set`:
        * Nas requisições, uma lista será lida, eliminando duplicadas e convertendo-a em um `set`.
