## ResourceModifiedEvent interface

Payload of the `resourceModified` event, emitted after this client instance successfully creates, updates, patches, or deletes a FHIR resource.

Emitted by `createResource`, `createResourceIfNoneExist`, `updateResource`, `upsertResource`, `patchResource`, `deleteResource`, and by `notifyResourceModified`. Conditional methods (`createResourceIfNoneExist`, `upsertResource`) emit even when the server made no change, except on HTTP 304 "Not Modified".

T - The type of the modified resource. Defaults to `Resource`; narrow it (e.g. via `useResourceModified('Slot', ...)`) to get a typed `resource` payload without extra guards.

**Signature:**  
```typescript  
export interface ResourceModifiedEvent<T extends Resource = Resource>  
```
