Crate cedarling 

Cedarling

The Cedarling is a performant local authorization service that runs the Rust Cedar Engine. Cedar policies and schema are loaded at startup from a locally cached “Policy Store”. In simple terms, the Cedarling returns the answer: should the application allow this action on this resource given these JWT tokens. “Fit for purpose” policies help developers build a better user experience. For example, why display form fields that a user is not authorized to see? The Cedarling is a more productive and flexible way to handle authorization.
