Class AsyncSubscriberClient (1.7.0)

AsyncSubscriberClient(
    *,
    nack_handler: Optional[
        google.cloud.pubsublite.cloudpubsub.nack_handler.NackHandler
    ] = None,
    reassignment_handler: Optional[
        google.cloud.pubsublite.cloudpubsub.reassignment_handler.ReassignmentHandler
    ] = None,
    message_transformer: Optional[
        google.cloud.pubsublite.cloudpubsub.message_transformer.MessageTransformer
    ] = None,
    credentials: Optional[google.auth.credentials.Credentials] = None,
    transport: str = "grpc_asyncio",
    client_options: Optional[google.api_core.client_options.ClientOptions] = None
)

An AsyncSubscriberClient reads messages similar to Google Pub/Sub, but must be used in an async context. Any subscribe failures are unlikely to succeed if retried.

Must be used in an async with block or have aenter() awaited before use.
