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]`.

{* ../../docs_src/server_sent_events/tutorial003_py310.py hl[17] *}

/// note | Nota

Das ist nützlich zum Senden vorformatierter Texte, Logzeilen oder spezieller <dfn title="Ein Wert, der verwendet wird, um eine besondere Bedingung oder einen besonderen Zustand anzuzeigen">„Sentinel“</dfn>-Werte wie `[DONE]`.

    It's used internally to recognize when a default value has been overwritten, even
    if the overridden default value was truthy.

    return DefaultPlaceholder(value)  # type: ignore


# Sentinel for "parameter not provided" in Param/FieldInfo.
# Typed as None to satisfy ty

Esto es útil para enviar texto preformateado, líneas de log, o valores especiales de <dfn title="Un valor usado para indicar una condición o estado especial">"centinela"</dfn> 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]`.

{* ../../docs_src/server_sent_events/tutorial003_py310.py hl[17] *}

/// 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.
type LruList[K comparable, V any] struct {
	root Entry[K, V] // sentinel list element, only &root, root.prev, and root.next are used
	len  int         // current list Length excluding (this) sentinel element
}

// Init initializes or clears list l.
func (l *LruList[K, V]) Init() *LruList[K, V] {
	l.root.next = &l.root
	l.root.prev = &l.root

C’est utile pour envoyer du texte préformaté, des lignes de log, ou des valeurs <dfn title="Une valeur utilisée pour indiquer une condition ou un état particulier">« sentinelle »</dfn> spéciales comme `[DONE]`.
