Interface IIdentifyResource<TResource, TId>

Namespace

Trellis.Authorization

Assembly

Trellis.Authorization.dll

Declares that this message carries a typed resource identifier that can be extracted for resource-based authorization. Implement alongside IAuthorizeResource<TResource> to use a SharedResourceLoaderById<TResource, TId> instead of a per-command ResourceLoaderById<TMessage, TResource, TId>.

public interface IIdentifyResource<TResource, out TId>

Type Parameters

TResource

The type of the resource to authorize against.

TId

The identifier type (e.g., OrderId).
