Se você precisar enviar dados sem codificação JSON, use `raw_data` em vez de `data`.

Isto é útil para enviar texto pré-formatado, linhas de log ou valores <dfn title="um valor usado para indicar uma condição ou estado especial">"sentinela"</dfn> especiais como `[DONE]`.

/// note | Nota

`data` y `raw_data` son mutuamente excluyentes. Solo puedes establecer uno de ellos en cada `ServerSentEvent`.

If you need to send data **without** JSON encoding, use `raw_data` instead of `data`.

This is useful for sending pre-formatted text, log lines, or special <dfn title="A value used to indicate a special condition or state">"sentinel"</dfn> values like `[DONE]`.

/// note

`data` and `raw_data` are mutually exclusive. You can only set one of them on each `ServerSentEvent`.

// The zero Value for LruList is an empty list ready to use.
