In this section we'll see how to use other middlewares.

## Adding ASGI middlewares { #adding-asgi-middlewares }

As **FastAPI** is based on Starlette and implements the <abbr title="Asynchronous Server Gateway Interface">ASGI</abbr> specification, you can use any ASGI middleware.

     * @return the number of consecutive heartbeat failures
     */
    public int getHeartbeatFailures() {
        return heartbeatFailures;
    }

    /**
     * Checks if this registration has expired based on the timeout.
     *
     * @param timeoutMs the timeout in milliseconds
     * @return true if the registration is expired

    public boolean isExpired(long timeoutMs) {

    TypeToken<?> unused = supertype.getSubtype(subtype.getRawType());
  }

  public void testGetSubtype_baseClassWithNoTypeArgs() {
    class SingleGenericExtendsBase<T> extends Base {}
    TypeToken<Base> supertype = new TypeToken<Base>() {};
    TypeToken<SingleGenericExtendsBase<String>> subtype =
        new TypeToken<SingleGenericExtendsBase<String>>() {};
    assertTrue(subtype.isSubtypeOf(supertype));

Por ejemplo, hay una <a href="https://hub.docker.com/_/python" class="external-link" target="_blank">Imagen de Python</a> oficial.

Y hay muchas otras imágenes para diferentes cosas como bases de datos, por ejemplo para:

func (h dataUsageHash) modAlt(cycle uint32, cycles uint32) bool {
	if cycles <= 1 {
		return cycles == 1
	}
	return uint32(xxhash.Sum64String(string(h))>>32)%(cycles) == cycle%cycles
}

// addChild will add a child based on its hash.
// If it already exists it will not be added again.
func (e *dataUsageEntry) addChild(hash dataUsageHash) {
	if _, ok := e.Children[hash.Key()]; ok {
		return
	}
	if e.Children == nil {
