# isRefreshing

Tests whether a success or failure carries active refresh progress.

## Signatures

```ts
export declare const isRefreshing: <A, E>(asyncData: AsyncData<A, E>) => asyncData is Refreshing<A, E>;
```

## Why

Refreshing keeps an existing result visible while making new work observable.

## Ownership and lifetime

This pure predicate acquires no resources and does not retain its argument.

## Examples

```ts
import { isRefreshing, success } from "@typed/async-data"
isRefreshing(success("cached", { loaded: 0 }))
```
