Struct OdrlEngine 

pub struct OdrlEngine { /* private fields */ }

An ODRL policy engine.

The engine holds a parsed OdrlDocument and evaluates requests against all matching rules. It applies ODRL’s conflict resolution: prohibitions take precedence over permissions when both match the same (subject, action, target).

Every check emits a structured OdrlAuditEvent via tracing.

Implementations

impl OdrlEngine

pub fn new(doc: OdrlDocument) -> OdrlEngine

Build an engine from a parsed document.

pub fn from_yaml(yaml: &str) -> Result<OdrlEngine, String>

Parse a YAML string and build an engine.

pub fn with_context(self, ctx: ConstraintContext) -> OdrlEngine

Override the default constraint context (e.g., set purpose for all checks).

pub fn check_with_context( &self, subject: &str, action: &str, resource: &str, ctx: &ConstraintContext, ) -> PolicyResult

Run a check with a specific context (overrides per-call).

Trait Implementations

impl PolicyEngine for OdrlEngine

fn check( &self, subject: &SubjectId, action: &str, resource: &ResourceId, ) -> PolicyResult

Evaluate whether subject may perform action on resource.

fn check_with_context( &self, subject: &SubjectId, action: &str, resource: &ResourceId, ctx: &RequestContext, ) -> PolicyResult

Evaluate a request with runtime context.

fn check_async<'a>( &'a self, subject: &'a SubjectId, action: &'a str, resource: &'a ResourceId, ) -> Pin<Box<dyn Future<Output = PolicyResult> + Send + 'a>>

Evaluate whether subject may perform action on resource asynchronously.

fn check_with_context_async<'a>( &'a self, subject: &'a SubjectId, action: &'a str, resource: &'a ResourceId, ctx: &'a RequestContext, ) -> Pin<Box<dyn Future<Output = PolicyResult> + Send + 'a>>

Evaluate a request with runtime context asynchronously.

fn with_fallback(self, fallback: Arc<dyn PolicyEngine>) -> FallbackEngine<Self>

where Self: Sized,

Compose this engine with a fallback.
