Struct CrueEngine 

pub struct CrueEngine { /* private fields */ }

CRUE Engine - main rule evaluation engine

Implementations

impl CrueEngine

pub fn new() -> Self

Create new CRUE engine

pub fn load_rules(&mut self, registry: RuleRegistry)

Load rules from legacy runtime registry.

pub fn load_compiled_rules(&mut self, rules: Vec<CompiledPolicyRule>)

Replace compiled rules (preferred execution path when non-empty).

pub fn register_compiled_rule_ast( &mut self, ast: &RuleAst, ) -> Result<(), EngineError>

Register a compiled rule from AST.

pub fn register_compiled_rule_source( &mut self, source: &str, ) -> Result<(), EngineError>

Register a compiled rule from DSL source.

pub fn clear_compiled_rules(&mut self)

Clear compiled rules and fall back to legacy runtime rules.

pub fn evaluate(&self, request: &EvaluationRequest) -> EvaluationResult

Evaluate request against compiled rules first, then legacy runtime rules.

pub fn evaluate_with_proof( &self, request: &EvaluationRequest, crypto_backend_id: &str, ) -> (EvaluationResult, Option<ProofBinding>)

Evaluate request and produce a strict ProofBinding when the compiled-bytecode path is used.

Returns (result, binding) where binding is:

• Some(..) when a compiled rule matched and binding generation succeeded
• None when evaluation used legacy runtime rules or no compiled rule matched

pub fn evaluate_with_signed_proof_ed25519( &self, request: &EvaluationRequest, crypto_backend_id: &str, signer_key_id: &str, key_pair: &Ed25519KeyPair, ) -> (EvaluationResult, Option<ProofEnvelope>)

Evaluate request and return a signed proof envelope (Ed25519 bootstrap signing).

The envelope is only produced when the compiled-bytecode path is used and a rule matches.

pub fn evaluate_with_signed_proof_v1_ed25519( &self, request: &EvaluationRequest, crypto_backend_id: &str, signer_key_id: &str, key_pair: &Ed25519KeyPair, ) -> (EvaluationResult, Option<ProofEnvelopeV1>)

Evaluate request and return a canonical ProofEnvelopeV1 signed with Ed25519.

pub fn set_strict_mode(&mut self, strict: bool)

Set strict mode

pub fn rule_count(&self) -> usize

Get total rule count (compiled + legacy runtime registry)

pub fn compiled_rule_count(&self) -> usize

Number of compiled rules loaded in VM path.

Trait Implementations

impl Default for CrueEngine

fn default() -> Self

Returns the “default value” for a type.
