Note: this value is the server's effective state, not necessarily what was requested. A rule saved via `BatchUpdateRulesRequest.override_expression_validation = true` whose UDF inlining fails (e.g. type resolution exhausted; see error returned by `BatchUpdateRules`) is forced to `is_live_evaluation_enabled = false` even when the caller requested `true`. To recover after the underlying issue is fixed (channels populated, expression simplified, etc.), reissue an `UpdateRule` / `BatchUpdateRules` request that explicitly sets `is_live_evaluation_enabled = true`. currentVersionId: type: string description: >- The current version of the rule. This is may be different from the rule_version.version if the rule has been updated since the rule_version was created. folderIds: type: array items: type: string description: Ids of the folders this rule belongs to. required: - ruleId - assetId - name - description - isEnabled - createdDate - modifiedDate - createdByUserId - modifiedByUserId - organizationId - conditions - ruleVersion - assetConfiguration - contextualChannels - isExternal - metadata - isArchived - currentVersionId protobufAny: type: object properties: '@type': type: string description: >- A URL/resource name that uniquely identifies the type of the serialized protocol buffer message. This string must contain at least one "/" character. The last segment of the URL's path must represent the fully qualified name of the type (as in `path/google.protobuf.Duration`). The name should be in a canonical form (e.g., leading "." is not accepted). In practice, teams usually precompile into the binary all types that they expect it to use in the context of Any. However, for URLs which use the scheme `http`, `https`, or no scheme, one can optionally set up a type server that maps type URLs to message definitions as follows: * If no scheme is provided, `https` is assumed. * An HTTP GET on the URL must yield a [google.protobuf.Type][] value in binary format, or produce an error. * Applications are allowed to cache lookup results based on the URL, or have them precompiled into a binary to avoid any lookup. Therefore, binary compatibility needs to be preserved on changes to types. (Use versioned type names to manage breaking changes.) Note: this functionality is not currently available in the official protobuf release, and it is not used for type URLs beginning with type.googleapis.com. As of May 2023, there are no widely used type server implementations and no plans to implement one. Schemes other than `http`, `https` (or the empty scheme) might be used with implementation specific semantics. additionalProperties: {} description: >- `Any` contains an arbitrary serialized protocol buffer message along with a URL that describes the type of the serialized message. Protobuf library provides support to pack/unpack Any values in the form of utility functions or additional generated methods of the Any type. Example 1: Pack and unpack a message in C++. Foo foo = ...; Any any; any.PackFrom(foo); ... if (any.UnpackTo(&foo)) { ... } Example 2: Pack and unpack a message in Java. Foo foo = ...; Any any = Any.pack(foo); ... if (any.is(Foo.class)) { foo = any.unpack(Foo.class); } // or ... if (any.isSameTypeAs(Foo.getDefaultInstance())) { foo = any.unpack(Foo.getDefaultInstance()); } Example 3: Pack and unpack a message in Python. foo = Foo(...) any = Any() any.Pack(foo) ... if any.Is(Foo.DESCRIPTOR): any.Unpack(foo) ... Example 4: Pack and unpack a message in Go foo := &pb.Foo{...} any, err := anypb.New(foo) if err != nil { ... } ... foo := &pb.Foo{} if err := any.UnmarshalTo(foo); err != nil { ... } The pack methods provided by protobuf library will by default use 'type.googleapis.com/full.type.name' as the type URL and the unpack methods only use the fully qualified type name after the last '/' in the type URL, for example "foo.bar.com/x/y.z" will yield type name "y.z". JSON ==== The JSON representation of an `Any` value uses the regular representation of the deserialized, embedded message, with an additional field `@type` which contains the type URL. Example: package google.profile; message Person { string first_name = 1; string last_name = 2; } { "@type": "type.googleapis.com/google.profile.Person", "firstName": , "lastName": } If the embedded message type is well-known and has a custom JSON representation, that representation will be embedded adding a field `value` which holds the custom JSON in addition to the `@type` field. Example (for message [google.protobuf.Duration][]): { "@type": "type.googleapis.com/google.protobuf.Duration", "value": "1.212s" } v2CalculatedChannelConfiguration: type: object properties: assetConfiguration: $ref: '#/components/schemas/v2CalculatedChannelAssetConfiguration' queryConfiguration: $ref: '#/components/schemas/v2CalculatedChannelQueryConfiguration' required: - assetConfiguration - queryConfiguration v1FunctionDependency: type: object properties: userDefinedFunctionVersionId: type: string required: - userDefinedFunctionVersionId v1MetadataValue: type: object properties: key: $ref: '#/components/schemas/v1MetadataKey' stringValue: type: string numberValue: type: number format: double booleanValue: type: boolean relationValue: $ref: '#/components/schemas/v1MetadataRelationValue' archivedDate: type: string format: date-time isArchived: type: boolean description: >- Whether the metadata value is archived.
