* Por exemplo, `await myfile.seek(0)` irá para o início do arquivo.
    * Isso é especialmente útil se você executar `await myfile.read()` uma vez e precisar ler o conteúdo novamente.
* `close()`: Fecha o arquivo.

Como todos esses métodos são métodos `assíncronos`, você precisa "aguardar" por eles.

Por exemplo, dentro de uma função de *operação de rota* `assíncrona`, você pode obter o conteúdo com:

```Python

					dest := db.Statement.Dest
					db.Statement.Dest = db.Statement.ReflectValue.Addr().Interface()
					gorm.Scan(rows, db, mode)
					db.Statement.Dest = dest
					db.AddError(rows.Close())

					if db.Statement.Result != nil {
						db.Statement.Result.RowsAffected = db.RowsAffected
					}
				}
			} else {

}

In fact, FastAPI uses those two decorators internally.

## A database dependency with `yield` { #a-database-dependency-with-yield }

For example, you could use this to create a database session and close it after finishing.

Only the code prior to and including the `yield` statement is executed before creating a response:
