# outcomes

[`outcomes()`](api:ruststream::testing::SubscriberAssertions::outcomes) returns how every handler call settled, in call order.

Each entry is an [`Outcome`](api:ruststream::testing::Outcome): `Ack`, `Nack`, `Drop`, `DecodeFailed` or `Panicked`.
[`settled`](./settled.md) and [`assert_outcome`](./assert-outcome.md) read the latest call only; `outcomes` pins a sequence, such as a nack followed by the ack of its redelivery.
A batch call has one entry, classified by its first delivery.
`Outcome` is `#[non_exhaustive]`, so a `match` on it needs a wildcard arm.

## Example

<Tabs groupId="api">
<TabItem value="macros" label="Macros">

```rust reference="examples/testing_subscriber_calls.rs#outcomes"
```

</TabItem>
<TabItem value="manual" label="Manual">

```rust reference="examples/manual/testing_subscriber_calls.rs#outcomes"
```

</TabItem>
