# xxHash3.StreamingState

> Type used to compute hash based on multiple data feed

## Definition

* **Type:** Struct
* **Namespace:** [Unity.Collections](/engine/6000.7/script-reference/unity/collections.md)
* **Assembly:** UnityEngine.ManagedKernelModule

```csharp
public struct xxHash3.StreamingState
```

## Remarks

Allow to feed the internal hashing accumulators with data through multiple calls to [xxHash3.StreamingState.Update](/engine/6000.7/script-reference/unity/collections/xxhash3/streamingstate/update.md), then retrieving the final hash value using [xxHash3.StreamingState.DigestHash64](/engine/6000.7/script-reference/unity/collections/xxhash3/streamingstate/digesthash64.md) or [xxHash3.StreamingState.DigestHash128](/engine/6000.7/script-reference/unity/collections/xxhash3/streamingstate/digesthash128.md).
