Operator-to-Middleware (O2M) request types.

Administrative requests from external operators, compliance officers, and organizations for policy management and provenance analysis. These operations typically require elevated privileges and are used for governance and audit purposes.

Variants

GetPolicies(HashSet<Resource>)

Retrieve current compliance policies for a set of resources.

Enables operators to audit current policy configurations and verify compliance with organizational or regulatory requirements.

SetPolicy

Set a complete compliance policy for a specific resource.

Replaces the existing policy with a new configuration that defines confidentiality, integrity, and access control requirements.

Fields

resource: Resource

Target resource to apply the policy to

policy: Policy

New policy configuration

SetConfidentiality

Set confidentiality requirements for a specific resource.

Updates only the confidentiality aspects of the resource’s policy, leaving other policy components unchanged.

Fields

resource: Resource

Target resource to update

confidentiality: ConfidentialityPolicy

New confidentiality policy requirements

SetIntegrity

Set integrity level requirements for a specific resource.

Updates the minimum integrity level required for data flows involving this resource, typically on a scale from 0 (lowest) to higher values.

Fields

resource: Resource

Target resource to update

integrity: u32

Minimum integrity level (higher values indicate stricter requirements)

SetDeleted(Resource)

Mark a resource as deleted for compliance and audit purposes.

Indicates that the resource has been removed from the system while preserving its historical provenance for audit trails.

SetConsent(Resource)

Grant consent for data processing operations on a resource.

Sets the consent flag to allow data flows and processing operations that require explicit permission, typically for privacy compliance.

GetReferences(Resource)

Retrieve the complete provenance lineage for a resource.

Returns all upstream resources and middleware nodes that have contributed data to the specified resource, enabling full traceability analysis.

Trait Implementations

impl<P, C> Service<O2mRequest> for O2mApiService<P, C>

where P: Service<ProvenanceRequest, Response = ProvenanceResponse, Error = TraceabilityError> + Clone + Send + NodeId + 'static, P::Future: Send, C: Service<ComplianceRequest, Response = ComplianceResponse, Error = TraceabilityError> + Clone + Send + 'static, C::Future: Send,

type Response = O2mResponse

Responses given by the service.

type Error = TraceabilityError

Errors produced by the service.

type Future = Pin<Box<dyn Future<Output = Result<<O2mApiService<P, C> as Service<O2mRequest>>::Response, <O2mApiService<P, C> as Service<O2mRequest>>::Error>> + Send>>

The future response value.

fn poll_ready(&mut self, _: &mut Context<'_>) -> Poll<Result<(), Self::Error>>

Returns Poll::Ready(Ok(())) when the service is able to process requests.

fn call(&mut self, request: O2mRequest) -> Self::Future

Process the request and return the response asynchronously.
