/**
 * 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). **JSON example:**
 * ``` { "bindings": [ { "role": "roles/resourcemanager.organizationAdmin", "members": [
 * "user:[email protected]", "group:[email protected]", "domain:google.com", "serviceAccount:my-
 * [email protected]" ] }, { "role":
 * "roles/resourcemanager.organizationViewer", "members": [ "user:[email protected]" ], "condition": {
 * "title": "expirable access", "description": "Does not grant access after Sep 2020", "expression":
 * "request.time < timestamp('2020-10-01T00:00:00.000Z')", } } ], "etag": "BwWWja0YfJA=", "version":
 * 3 } ``` **YAML example:** ``` bindings: - members: - user:[email protected] -
 * group:[email protected] - domain:google.com - serviceAccount:my-project-
 * [email protected] role: roles/resourcemanager.organizationAdmin - members: -
 * user:[email protected] role: roles/resourcemanager.organizationViewer condition: title: expirable
 * access description: Does not grant access after Sep 2020 expression: request.time <
 * timestamp('2020-10-01T00:00:00.000Z') etag: BwWWja0YfJA= version: 3 ``` For a description of IAM
 * and its features, see the [IAM documentation](https://cloud.google.com/iam/docs/).
