Module permission 

Permission-policy helpers that produce a handler::PermissionHandler. Permission policy primitives that produce a PermissionHandler.

Compose these into a session via the builder methods SessionConfig::approve_all_permissions, deny_all_permissions, and approve_permissions_if. The same primitives are also available as standalone functions that return an Arc<dyn PermissionHandler> you can install via SessionConfig::with_permission_handler.

For a one-shot approve / deny without composition, see ApproveAllHandler and DenyAllHandler.

Functions

approve_all

Return a PermissionHandler that approves every request.

approve_if

deny_all
