Struct google_api_proto::google::iam::v1::Policy

pub struct Policy {
    pub version: i32,
    pub bindings: Vec<Binding>,
    pub audit_configs: Vec<AuditConfig>,
    pub etag: Bytes,
}

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.

JSON example:

     {
       "bindings": [
         {
           "role": "roles/resourcemanager.organizationAdmin",
           "members": [
             "user:mike@example.com",
             "group:admins@example.com",
             "domain:google.com",
             "serviceAccount:my-project-id@appspot.gserviceaccount.com"
           ]
         },
         {
           "role": "roles/resourcemanager.organizationViewer",
           "members": [
             "user:eve@example.com"
           ],
           "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:mike@example.com
       - group:admins@example.com
       - domain:google.com
       - serviceAccount:my-project-id@appspot.gserviceaccount.com
       role: roles/resourcemanager.organizationAdmin
     - members:
       - user:eve@example.com
       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

Fields

version: i32

Specifies the format of the policy.

Valid values are 0, 1, and 3. Requests that specify an invalid value are rejected.

Any operation that affects conditional role bindings must specify version 3. This requirement applies to the following operations:

• Getting a policy that includes a conditional role binding
• Adding a conditional role binding to a policy
• Changing a conditional role binding in a policy
• Removing any role binding, with or without a condition, from a policy that includes conditions

Important: If you use IAM Conditions, you must include the etag field whenever you call setIamPolicy. If you omit this field, then IAM allows you to overwrite a version 3 policy with a version 1 policy, and all of the conditions in the version 3 policy are lost.

If a policy does not include any conditions, operations on that policy may specify any valid version or leave the field unset.

To learn which resources support conditions in their IAM policies, see the IAM documentation.

bindings: Vec<Binding>

Associates a list of members, or principals, with a role. Optionally, may specify a condition that determines how and when the bindings are applied. Each of the bindings must contain at least one principal.

The bindings in a Policy can refer to up to 1,500 principals; up to 250 of these principals can be Google groups. Each occurrence of a principal counts towards these limits. For example, if the bindings grant 50 different roles to user:alice@example.com, and not to any other principal, then you can add another 1,450 principals to the bindings in the Policy.

audit_configs: Vec<AuditConfig>

Specifies cloud audit logging configuration for this policy.

etag: Bytes

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.

Important: If you use IAM Conditions, you must include the etag field whenever you call setIamPolicy. If you omit this field, then IAM allows you to overwrite a version 3 policy with a version 1 policy, and all of the conditions in the version 3 policy are lost.

Trait Implementations

impl Clone for Policy

fn clone(&self) -> Policy

Returns a copy of the value.

fn clone_from(&mut self, source: &Self)

Performs copy-assignment from source.

impl Debug for Policy

fn fmt(&self, f: &mut Formatter<'_>) -> Result

Formats the value using the given formatter.

impl Default for Policy

fn default() -> Self

Returns the “default value” for a type.

impl Message for Policy

fn encoded_len(&self) -> usize

Returns the encoded length of the message without a length delimiter.

fn clear(&mut self)

Clears the message, resetting all fields to their default.

fn encode(&self, buf: &mut impl BufMut) -> Result<(), EncodeError>

where Self: Sized,

Encodes the message to a buffer.

fn encode_to_vec(&self) -> Vec<u8>

where Self: Sized,

Encodes the message to a newly allocated buffer.

fn encode_length_delimited( &self, buf: &mut impl BufMut, ) -> Result<(), EncodeError>

where Self: Sized,

Encodes the message with a length-delimiter to a buffer.

fn encode_length_delimited_to_vec(&self) -> Vec<u8>

where Self: Sized,

Encodes the message with a length-delimiter to a newly allocated buffer.

fn decode(buf: impl Buf) -> Result<Self, DecodeError>

where Self: Default,

Decodes an instance of the message from a buffer.

fn decode_length_delimited(buf: impl Buf) -> Result<Self, DecodeError>

fn merge(&mut self, buf: impl Buf) -> Result<(), DecodeError>

fn merge_length_delimited(&mut self, buf: impl Buf) -> Result<(), DecodeError>

impl PartialEq for Policy

fn eq(&self, other: &Policy) -> bool

This method tests for self and other values to be equal, and is used by ==.

fn ne(&self, other: &Rhs) -> bool

This method tests for !=. The default implementation is almost always sufficient, and should not be overridden without very good reason.
