Struct CompositeEngine 

pub struct CompositeEngine { /* private fields */ }

A validation engine that composes two engines: one owns the built-in rules, the other evaluates the caller-supplied Rego rules.

The built-in rules are always evaluated by the CEL engine, which also evaluates custom CEL rules (a CEL-engine feature) and Guard rules (which every engine evaluates through the shared Guard evaluator, so the built-in engine is as good a host as any). Custom Rego rules need a Rego engine, so one is built in external-only mode - contributing no built-in findings of its own - and only when the configuration supplies Rego rules. Findings from both are concatenated; the surrounding validation pipeline performs the single finalize pass (dedup, sort, filter, enrich).

Implementations

impl CompositeEngine

pub fn new(config: CompositeEngineConfig) -> Result<CompositeEngine, Error>

Builds the composite engine from a CompositeEngineConfig. The built-in engine is always constructed; the external engine is constructed only when the configuration supplies custom Rego rules.

Trait Implementations

impl ValidationEngine for CompositeEngine

fn external_rule_metadata(&self) -> HashMap<String, RuleMetadataEntry>

The external rule metadata is the union of both engines’ external rules: custom CEL and Guard rules from the built-in engine and custom Rego rules from the external engine. The two sets have disjoint rule IDs, so a plain merge cannot drop or overwrite a rule.

fn engine_name(&self) -> &str

fn evaluate_rules( &self, model: &Arc<SemanticModel>, config: &ValidateConfig, ) -> Result<Vec<Diagnostic>, ValidationError>

fn list_rules(&self) -> Vec<RuleInfo>

fn rule_metadata(&self) -> &HashMap<String, RuleMetadataEntry>

Built-in rule metadata from the rules registry only.
