El programa de línea de comandos llamado `fastapi` es **FastAPI CLI**.

FastAPI CLI toma el path de tu programa Python (por ejemplo, `main.py`), detecta automáticamente la `FastAPI` instance (comúnmente llamada `app`), determina el proceso de import correcto, y luego la sirve.

Para producción usarías `fastapi run` en su lugar. 🚀

the preceding example we used a field, `callStartNanos`, to track the elapsed time of each event. This is handy, but it won’t work if multiple calls are executing concurrently. To accommodate this, use a `Factory` to create a new `EventListener` instance for each `Call`. This allows each listener to keep call-specific state.

This [sample factory](https://github.com/square/okhttp/blob/master/samples/guide/src/main/java/okhttp3/recipes/PrintEvents.java) creates a unique ID for each call...
