 - `data`: the result of the asynchronous function that is passed in.
 - `pending`: a boolean indicating whether the data is still being fetched.
 - `refresh`/`execute`: a function that can be used to refresh the data returned by the `handler` function.
+- `clear`: a function that can be used to empty the state of `data` (and prevent any currently pending requests from updating it)
 - `error`: an error object if the data fetching failed.
 - `status`: a string indicating the status of the data request (`"idle"`, `"pending"`, `"success"`, `"error"`).
