A strategy that handles exhaustion of a buffer’s capacity.

```
enum BufferingPolicy
```

## Topics

### Buffering Policies

[`AsyncStream.Continuation.BufferingPolicy.unbounded`](/documentation/Swift/AsyncStream/Continuation/BufferingPolicy/unbounded)

Continue to add to the buffer, without imposing a limit on the number
of buffered elements.

[`AsyncStream.Continuation.BufferingPolicy.bufferingOldest(_:)`](/documentation/Swift/AsyncStream/Continuation/BufferingPolicy/bufferingOldest(_:))

When the buffer is full, discard the newly received element.

[`AsyncStream.Continuation.BufferingPolicy.bufferingNewest(_:)`](/documentation/Swift/AsyncStream/Continuation/BufferingPolicy/bufferingNewest(_:))

When the buffer is full, discard the oldest element in the buffer.
