PermitEx.Policy behaviour (permit_ex v0.3.0)

Copy Markdown View Source

Behaviour for optional resource-level policy checks.

RBAC answers whether a scope has a permission. A policy can answer whether that scope may use the permission against a specific resource.

The third argument receives the full options keyword list passed to PermitEx.allowed?/4 or PermitEx.authorize/4 (including :policy itself).
