# AllocatorManager.Range

> A range of allocated memory.

## Definition

* **Type:** Struct
* **Namespace:** [Unity.Collections](/engine/6000.7/script-reference/unity/collections.md)
* **Assembly:** UnityEngine.ManagedKernelModule
* **Implements:** [IDisposable](https://learn.microsoft.com/dotnet/api/system.idisposable)

```csharp
public struct AllocatorManager.Range : IDisposable
```

## Remarks

The name is perhaps misleading: only in combination with a [AllocatorManager.Block](/engine/6000.7/script-reference/unity/collections/allocatormanager/block.md) does a `Range` have sufficient information to represent the number of bytes in an allocation. The reason `Range` is its own type that's separate from `Block` stems from some efficiency concerns in the implementation details. In most cases, a `Range` is only used in conjunction with an associated `Block`.
