## Was ist ein Stream? { #what-is-a-stream }

„Streaming“ von Daten bedeutet, dass Ihre App damit beginnt, Datenelemente an den Client zu senden, ohne darauf zu warten, dass die gesamte Folge von Elementen fertig ist.

/**
 * Package-protected abstract class that implements the line reading algorithm used by {@link

Calls can be canceled from any thread. This will fail the call if it hasn’t yet completed! Code that is writing the request body or reading the response body will suffer an `IOException` when its call is canceled.

It has:

* Seriously impressive performance.
* WebSocket support.
* In-process background tasks.
* Startup and shutdown events.
* Test client built on HTTPX.
* CORS, GZip, Static Files, Streaming responses.
* Session and Cookie support.
* 100% test coverage.
* 100% type annotated codebase.
* Few hard dependencies.
