### Method Details

`create(name, body=None, x__xgafv=None)`

    Creates a snapshot from the requested subscription. Snapshots are used in
    [Seek](https://cloud.google.com/pubsub/docs/replay-overview) operations,
    which allow you to manage message acknowledgments in bulk. That is, you can
    set the acknowledgment state of messages in an existing subscription to the
    state captured by a snapshot.
    If the snapshot already exists, returns `ALREADY_EXISTS`.
    If the requested subscription doesn't exist, returns `NOT_FOUND`.
    If the backlog in the subscription is too old -- and the resulting snapshot
    would expire in less than 1 hour -- then `FAILED_PRECONDITION` is returned.
    See also the `Snapshot.expire_time` field. If the name is not provided in
    the request, the server will assign a random
    name for this snapshot on the same project as the subscription, conforming
    to the [resource name format]
    (https://cloud.google.com/pubsub/docs/admin#resource_names). The
    generated name is populated in the returned Snapshot object. Note that for
    REST API requests, you must specify a name in the request.

    Args:
      name: string, Required. User-provided name for this snapshot. If the name is not provided in the
    request, the server will assign a random name for this snapshot on the same
    project as the subscription. Note that for REST API requests, you must
    specify a name.  See the <a
    href="https://cloud.google.com/pubsub/docs/admin#resource_names"> resource
    name rules</a>. Format is `projects/{project}/snapshots/{snap}`. (required)
      body: object, The request body.
        The object takes the form of:

    { # Request for the `CreateSnapshot` method.
        "labels": { # See <a href="https://cloud.google.com/pubsub/docs/labels"> Creating and
            # managing labels</a>.
          "a_key": "A String",
        },
        "subscription": "A String", # Required. The subscription whose backlog the snapshot retains.
            # Specifically, the created snapshot is guaranteed to retain:
            #  (a) The existing backlog on the subscription. More precisely, this is
            #      defined as the messages in the subscription's backlog that are
            #      unacknowledged upon the successful completion of the
            #      `CreateSnapshot` request; as well as:
            #  (b) Any messages published to the subscription's topic following the
            #      successful completion of the CreateSnapshot request.
            # Format is `projects/{project}/subscriptions/{sub}`.
      }

        Allowed values
          1 - v1 error format
          2 - v2 error format

    Returns:
      An object of the form:

            # backlog in the source subscription. Specifically, the lifetime of the
            # snapshot is `7 days - (age of oldest unacked message in the subscription)`.
            # For example, consider a subscription whose oldest unacked message is 3 days
            # old. If a snapshot is created from this subscription, the snapshot -- which
            # will always capture this 3-day-old backlog as long as the snapshot
            # exists -- will expire in 4 days. The service will refuse to create a
            # snapshot that would expire in less than 1 hour after creation.

`delete(snapshot, x__xgafv=None)`

    Removes an existing snapshot. Snapshots are used in [Seek]
    (https://cloud.google.com/pubsub/docs/replay-overview) operations, which
    allow you to manage message acknowledgments in bulk. That is, you can set
    the acknowledgment state of messages in an existing subscription to the
    state captured by a snapshot.
    When the snapshot is deleted, all messages retained in the snapshot
    are immediately dropped. After a snapshot is deleted, a new one may be
    created with the same name, but the new one has no association with the old
    snapshot or its subscription, unless the same subscription is specified.

    Args:
      snapshot: string, Required. The name of the snapshot to delete.
    Format is `projects/{project}/snapshots/{snap}`. (required)
      x__xgafv: string, V1 error format.
        Allowed values
          1 - v1 error format
          2 - v2 error format

    Returns:
      An object of the form:

        { # A generic empty message that you can re-use to avoid defining duplicated
          # empty messages in your APIs. A typical example is to use it as the request
          # or the response type of an API method. For instance:
          #
          #     service Foo {
          #       rpc Bar(google.protobuf.Empty) returns (google.protobuf.Empty);
          #     }

`getIamPolicy(resource, options_requestedPolicyVersion=None, x__xgafv=None)`

    Gets the access control policy for a resource.
    Returns an empty policy if the resource exists and does not have a policy
    set.

    Args:
      resource: string, REQUIRED: The resource for which the policy is being requested.

    Valid values are 0, 1, and 3. Requests specifying an invalid value will be
    rejected.

    Requests for policies with any conditional bindings must specify version 3.
    Policies without any conditional bindings may specify any valid value or
    leave the field unset.

          #
          # A `Policy` is a collection of `bindings`. A `binding` binds one or more
          # `members` to a single `role`. Members 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

`list(project, pageToken=None, pageSize=None, x__xgafv=None)`

    Lists the existing snapshots. Snapshots are used in [Seek](
    https://cloud.google.com/pubsub/docs/replay-overview) operations, which
    allow you to manage message acknowledgments in bulk. That is, you can set
    the acknowledgment state of messages in an existing subscription to the
    state captured by a snapshot.

    Args:
      project: string, Required. The name of the project in which to list snapshots.
    Format is `projects/{project-id}`. (required)
      pageToken: string, The value returned by the last `ListSnapshotsResponse`; indicates that this
    is a continuation of a prior `ListSnapshots` call, and that the system
    should return the next page of data.
      pageSize: integer, Maximum number of snapshots to return.
      x__xgafv: string, V1 error format.
        Allowed values
          1 - v1 error format
          2 - v2 error format

`testIamPermissions(resource, body=None, x__xgafv=None)`

    Returns permissions that a caller has on the specified resource.
    If the resource does not exist, this will return an empty set of
    permissions, not a `NOT_FOUND` error.

    Note: This operation is designed to be used for building permission-aware
    UIs and command-line tools, not for authorization checking. This operation
    may "fail open" without warning.

    Args:
      resource: string, REQUIRED: The resource for which the policy detail is being requested.
    See the operation documentation for the appropriate value for this field. (required)
      body: object, The request body.
        The object takes the form of:

    { # Request message for `TestIamPermissions` method.
        "permissions": [ # The set of permissions to check for the `resource`. Permissions with
            # wildcards (such as '*' or 'storage.*') are not allowed. For more
            # information see

      x__xgafv: string, V1 error format.
        Allowed values
          1 - v1 error format
          2 - v2 error format

    Returns:
      An object of the form:

        { # Response message for `TestIamPermissions` method.
        "permissions": [ # A subset of `TestPermissionsRequest.permissions` that the caller is
            # allowed.
