## Server-Sent Events (SSE)

To stream Server-Sent Events, use `response_class=EventSourceResponse` and `yield` items from the endpoint.

Plain objects are automatically JSON-serialized as `data:` fields, declare the return type so the serialization is done by Pydantic:

```python
from collections.abc import AsyncIterable

from fastapi import FastAPI
from fastapi.sse import EventSourceResponse

			if err != nil {
				err = msgp.WrapError(err)
				return
			}
		}
	}
	o = bts
	return
}

// Msgsize returns an upper bound estimate of the number of bytes occupied by the serialized message
func (z *PoolDecommissionInfo) Msgsize() (s int) {

  }

  @Override
  public boolean isEmpty() {
    return delegateCollection().isEmpty();
  }

  @Override
  boolean isPartialView() {
    return delegateCollection().isPartialView();
  }

  /** Serialized form that leads to the same performance as the original list. */
  @GwtIncompatible
  @J2ktIncompatible
  private static final class SerializedForm implements Serializable {
    final ImmutableCollection<?> collection;

					return
				}
			}
		}
		(*z)[zb0001] = zb0002
	}
	o = bts
	return
}

// Msgsize returns an upper bound estimate of the number of bytes occupied by the serialized message
func (z DailyAllTierStats) Msgsize() (s int) {
	s = msgp.MapHeaderSize
	if z != nil {
		for zb0007, zb0008 := range z {
			_ = zb0008

    * Pydantic, bunu ayrıca bir "ISO 8601 time diff encoding" olarak temsil etmeye de izin verir, [daha fazla bilgi için dokümanlara bakın](https://docs.pydantic.dev/latest/concepts/serialization/#custom-serializers).
* `frozenset`:
    * request'lerde ve response'larda, `set` ile aynı şekilde ele alınır:
        * request'lerde bir list okunur, tekrarlar kaldırılır ve `set`'e dönüştürülür.

/// warning | Atenção

Quando você retorna um `Response` diretamente, como no exemplo acima, ele será retornado diretamente.

Ele não será serializado com um modelo, etc.

Garanta que ele tenha toda informação que você deseja, e que os valores sejam um JSON válido (caso você esteja usando `JSONResponse`).

* `frozenset`:
    * У запитах і відповідях це буде оброблено так само, як і `set`:
        * У запитах список буде зчитано, дублікати буде видалено, і його буде перетворено на `set`.
