class InstanceAdminRestInterceptor:
    """Interceptor for InstanceAdmin.

    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 InstanceAdminRestTransport.

    Cloud Spanner Instance Admin API

    The Cloud Spanner Instance Admin API can be used to create,
    delete, modify and list instances. Instances are dedicated Cloud
    Spanner serving and storage resources to be used by Cloud
    Spanner databases.

    Each instance has a "configuration", which dictates where the
    serving resources for the Cloud Spanner instance are located
    (e.g., US-central, Europe). Configurations are created by Google
    based on resource availability.

    Cloud Spanner billing is based on the instances that exist and
    their sizes. After an instance exists, there are no additional
    per-database or per-operation charges for use of the instance
    (though there may be additional network bandwidth charges).
    Instances offer isolation: problems with databases in one
    instance will not affect other instances. However, within an
    instance databases can affect each other. For example, if one
    database in an instance receives a lot of requests and consumes
    most of the instance resources, fewer resources are available
    for other databases in that instance, and their performance may
    suffer.

    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

                    An Identity and Access Management (IAM) policy, which
                specifies access controls for Google Cloud resources.

                A ``Policy`` is a collection of ``bindings``. A
                ``binding`` binds one or more ``members``, or
                principals, to a single ``role``. Principals can be user
                accounts, service accounts, Google groups, and domains
                (such as G Suite). A ``role`` is a named list of
                permissions; each ``role`` can be an IAM predefined role
                or a user-created custom role.

                For some types of Google Cloud resources, a ``binding``
                can also specify a ``condition``, which is a logical
                expression that allows access to a resource only if the
                expression evaluates to ``true``. A condition can add
                constraints based on attributes of the request, the
                resource, or both. To learn which resources support
                conditions in their IAM policies, see the `IAM
                documentation <https://cloud.google.com/iam/help/conditions/resource-policies>`__.

                    An Identity and Access Management (IAM) policy, which
                specifies access controls for Google Cloud resources.

                A ``Policy`` is a collection of ``bindings``. A
                ``binding`` binds one or more ``members``, or
                principals, to a single ``role``. Principals can be user
                accounts, service accounts, Google groups, and domains
                (such as G Suite). A ``role`` is a named list of
                permissions; each ``role`` can be an IAM predefined role
                or a user-created custom role.

                For some types of Google Cloud resources, a ``binding``
                can also specify a ``condition``, which is a logical
                expression that allows access to a resource only if the
                expression evaluates to ``true``. A condition can add
                constraints based on attributes of the request, the
                resource, or both. To learn which resources support
                conditions in their IAM policies, see the `IAM
                documentation <https://cloud.google.com/iam/help/conditions/resource-policies>`__.
