Primarily for historical reasons, ingestion is split into a few components.

     * checkers are unlikely to ever look at the annotations on this declaration.

     * Historical note: At one point, we'd declared this method as accepting and returning nullable
     * values. For details on that, see earlier revisions of this file.

Mas os detalhes entre *concorrência* e *paralelismo* são bem diferentes.

Para ver essa diferença, imagine a seguinte história sobre hambúrgueres:

### Hambúrgueres concorrentes

Você vai com seu _crush_ :heart_eyes: na lanchonete, fica na fila enquanto o caixa pega os pedidos das pessoas na sua frente.

¡No! Esa no es la moraleja de la historia.

La concurrencia es diferente al paralelismo. Y es mejor en escenarios **específicos** que implican mucha espera. Debido a eso, generalmente es mucho mejor que el paralelismo para el desarrollo de aplicaciones web. Pero no para todo.

Entonces, para explicar eso, imagina la siguiente historia corta:

> Tienes que limpiar una casa grande y sucia.

		s = s[1:]
	}
	if len(s) == 0 {
		// This is what we've historically done.
		return nil
	}
	return s
}

func trimLeftASCII(s []byte, as *asciiSet) []byte {
	for len(s) > 0 {
		if !as.contains(s[0]) {
			break
		}
		s = s[1:]
	}
	if len(s) == 0 {
		// This is what we've historically done.
		return nil
	}
	return s
}

A secondary goal was to enable a smoother on-ramp from "Zero" to "Getting some value".
Historically, Istio had to really be consumed all-or-nothing for things to work as expected.
In particular, an easy answer to "I just want to have mTLS everywhere, then I can think about adopting the rest of service mesh" was desired.
