# Changelog



## 0.1.0



First release. Parc models a PARC (Principal, Action, Resource, Context)

authorization request and the decision over it, independent of any policy

framework.



- `Parc.Request`, the Principal/Action/Resource/Context request a decision is

  made on.

- `Parc.RequestPreparer`, the behaviour for a step that enriches the request or

  aborts with an error, and cannot decide a verdict.

- `Parc.PolicyDecider`, the behaviour for the single decision point, returning

  an allow, deny, challenge, or error verdict.

- `Parc.Pipeline`, which runs the declared preparers and then the decider, and

  the `use Parc.Pipeline` builder whose `prepare` and `decide` macros enforce

  exactly one decider at compile time.
