Enum PreparedEngine 

pub enum PreparedEngine {
    SchemaFree(PolicyEngine<SchemaFree>),
    SchemaEnforcing(PolicyEngine<SchemaEnforcing>),
}

A prepared engine retaining the bundle’s schema validation capability.

Match the variant to access mode-specific Core operations. A schema-free engine cannot be represented as schema-enforcing:

use treetop_bundle::PreparedEngine;
use treetop_core::PolicyEngine;
let free = PolicyEngine::new_from_str("").unwrap();
let enforcing = PreparedEngine::SchemaEnforcing(free);

Variants

SchemaFree(PolicyEngine<SchemaFree>)

A bundle without an enforcing Cedar schema.

SchemaEnforcing(PolicyEngine<SchemaEnforcing>)

A bundle with a fully validated, enforcing Cedar schema.

Implementations

impl PreparedEngine

pub fn with_label_registry(self, registry: LabelRegistry) -> Self

Install a validated registry while retaining the engine’s schema mode.

pub fn session(&self) -> PreparedEvaluationSession

Capture one complete generation for all evaluations and version reporting.

pub fn current_version(&self) -> PolicyVersion

Return the current complete authorization-state version.

pub fn policy_store_ids(&self) -> Option<Vec<PolicyStoreId>>

Return configured store IDs, or None for a monolithic engine.

pub fn list_policies_for_user( &self, user: &str, groups: &[&str], namespace: &[&str], ) -> Result<PolicyCandidates, PolicyError>

List structural permit-policy candidates; these do not authorize operations.

Returns Core validation errors for malformed principal inputs.

pub fn evaluate(&self, request: &Request) -> Result<Decision, PolicyError>

Evaluate a request, returning Core errors for invalid request data.

pub fn evaluate_with_context( &self, request: &Request, context: &RequestContext, ) -> Result<Decision, PolicyError>

Evaluate with explicit context, returning Core validation/evaluation errors.

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

Performs copy-assignment from source.

impl From<PolicyEngine<SchemaEnforcing>> for PreparedEngine

fn from(engine: PolicyEngine<SchemaEnforcing>) -> Self
