defmodule GoogleApi.Spanner.V1.Model.Policy do
  @moduledoc """
  Defines an Identity and Access Management (IAM) policy. It is used to specify access control policies for Cloud Platform resources.   A `Policy` consists of a list of `bindings`. A `binding` binds a list of `members` to a `role`, where the members can be user accounts, Google groups, Google domains, and service accounts. A `role` is a named list of permissions defined by IAM.  **JSON Example**      {       \"bindings\": [         {           \"role\": \"roles/owner\",           \"members\": [             \"user:mike@example.com\",             \"group:admins@example.com\",             \"domain:google.com\",             \"serviceAccount:my-other-app@appspot.gserviceaccount.com\"           ]         },         {           \"role\": \"roles/viewer\",           \"members\": [\"user:sean@example.com\"]         }       ]     }  **YAML Example**      bindings:     - members:       - user:mike@example.com       - group:admins@example.com       - domain:google.com       - serviceAccount:my-other-app@appspot.gserviceaccount.com       role: roles/owner     - members:       - user:sean@example.com       role: roles/viewer   For a description of IAM and its features, see the [IAM developer's guide](https://cloud.google.com/iam/docs).

  ## Attributes

  - bindings ([Binding]): Associates a list of `members` to a `role`. `bindings` with no members will result in an error. Defaults to: `null`.
  - etag (binary()): `etag` is used for optimistic concurrency control as a way to help prevent simultaneous updates of a policy from overwriting each other. It is strongly suggested that systems make use of the `etag` in the read-modify-write cycle to perform policy updates in order to avoid race conditions: An `etag` is returned in the response to `getIamPolicy`, and systems are expected to put that etag in the request to `setIamPolicy` to ensure that their change will be applied to the same version of the policy.  If no `etag` is provided in the call to `setIamPolicy`, then the existing policy is overwritten blindly. Defaults to: `null`.
  - version (integer()): Deprecated. Defaults to: `null`.
