Struct PolicyEngine 

pub struct PolicyEngine { /* private fields */ }

Policy evaluation engine.

Rules are evaluated in order; first match wins. When no profile is loaded, all actions are allowed.

Implementations

impl PolicyEngine

pub fn new() -> Self

Create an empty policy engine (allows everything) with default ConflictResolutionStrategy::PriorityFirstMatch.

pub fn with_strategy(strategy: ConflictResolutionStrategy) -> Self

Create a policy engine with a specific conflict resolution strategy.

pub fn strategy(&self) -> ConflictResolutionStrategy

Return the active conflict resolution strategy.

pub fn resolve_conflicts( &self, candidates: &[CandidateDecision], ) -> ResolutionResult

Resolve conflicts among multiple candidate decisions using the configured strategy.

Returns a ResolutionResult describing which decision won, whether a conflict was detected, and how many candidates were evaluated.

pub fn is_loaded(&self) -> bool

Whether a policy profile is loaded.

pub fn load_from_yaml(&self, yaml: &str) -> Result<(), PolicyError>

Load a policy profile from a YAML string.

pub fn load_from_file(&self, path: &str) -> Result<(), PolicyError>

Load a policy profile from a YAML file on disk.

pub fn evaluate( &self, action: &str, context: Option<&HashMap<String, Value>>, ) -> PolicyDecision

Evaluate an action against the loaded policy.

If no profile is loaded, returns PolicyDecision::Allow. An optional context map is matched against rule conditions.
