Trait PdpResolver

External policy-decision dispatch. Implemented by Cedar, OPA HTTP clients, AuthZen clients, NeMo Guardrails — anything that can answer “given this call, allow or deny?” against a request context.

apl-cpex provides the bridge from CPEX plugins (e.g. cedar-direct) to this trait so the host doesn’t have to know about the plugin types.

Required Methods

fn dialect(&self) -> PdpDialect

What dialect this resolver handles. The evaluator routes PDP steps to the resolver whose dialect() matches Step::Pdp.call.dialect.

fn evaluate<'life0, 'life1, 'life2, 'async_trait>( &'life0 self, call: &'life1 PdpCall, bag: &'life2 AttributeBag, ) -> Pin<Box<dyn Future<Output = Result<PdpDecision, PdpError>> + Send + 'async_trait>>

where Self: 'async_trait, 'life0: 'async_trait, 'life1: 'async_trait, 'life2: 'async_trait,

Dyn Compatibility

This trait is dyn compatible.

In older versions of Rust, dyn compatibility was called "object safety".
