# getError

Returns the first typed failure found in a Failure Cause.

## Signatures

```ts
export declare function getError<A, E>(data: AsyncData<A, E>): Option.Option<E>;
```

## Why

This convenience accessor intentionally excludes defects and interruption; use `getCause` when those distinctions matter.

## Ownership and lifetime

This pure lookup acquires no resources and does not retain the state.

## Examples

```ts
import { failure, getError } from "@typed/async-data"
import { Cause } from "effect"
const error = getError(failure(Cause.fail("offline")))
```
