class FirestoreAdminRestInterceptor:
    """Interceptor for FirestoreAdmin.

    Interceptors are used to manipulate requests, request metadata, and responses
    in arbitrary ways.
    Example use cases include:
    * Logging
    * Verifying requests according to service or custom semantics
    * Stripping extraneous information from responses

    These use cases and more can be enabled by injecting an
    instance of a custom subclass when constructing the FirestoreAdminRestTransport.

    The Cloud Firestore Admin API.

    This API provides several administrative services for Cloud
    Firestore.

    Project, Database, Namespace, Collection, Collection Group, and
    Document are used as defined in the Google Cloud Firestore API.

    Operation: An Operation represents work being performed in the
    background.

    The index service manages Cloud Firestore indexes.

    Index creation is performed asynchronously. An Operation resource is
    created for each such asynchronous operation. The state of the
    operation (including any errors encountered) may be queried via the
    Operation resource.

    The Operations collection provides a record of actions performed for
    the specified Project (including any Operations in progress).
    Operations are not created directly but through calls on other
    collections or resources.

    An Operation that is done may be deleted so that it is no longer
    listed as part of the Operation collection. Operations are garbage
    collected after 30 days. By default, ListOperations will only return
    in progress and failed operations. To list completed operation,
    issue a ListOperations request with the filter ``done: true``.

    Operations are created by service ``FirestoreAdmin``, but are
    accessed via service ``google.longrunning.Operations``.

    This class defines the same methods as the primary client, so the
    primary client can load the underlying transport implementation
    and call it.

    It sends JSON representations of protocol buffers over HTTP/1.1
