# NativeSlice<T>

> Provides a view on a buffer of native memory most commonly acquired from a NativeArray<T>.

## Definition

* **Type:** Struct
* **Namespace:** [Unity.Collections](/engine/6000.7/script-reference/unity/collections.md)
* **Assembly:** UnityEngine.ManagedKernelModule
* **Implements:** [IEnumerable\<T>](https://learn.microsoft.com/dotnet/api/system.collections.generic.ienumerable-1), [IEnumerable](https://learn.microsoft.com/dotnet/api/system.collections.ienumerable), [IEquatable\<NativeSlice\<T>>](https://learn.microsoft.com/dotnet/api/system.iequatable-1)

```csharp
public struct NativeSlice<T> : IEnumerable<T>, IEnumerable, IEquatable<NativeSlice<T>> where T : struct
```

## Remarks

A `NativeSlice` includes safety mechanisms for use with the job system. A `NativeSlice` doesn't own any memory allocations and can't be disposed, unlike a `NativeArray`[NativeArray\<T>](/engine/6000.7/script-reference/unity/collections/nativearray1.md).

A `NativeSlice` supports a stride value and doesn't necessarily represent a contiguous memory range. The stride value determines the number of bytes from the first byte of the element to the first byte of the next element. The stride value must always be a multiple of the size of the type of the slice in bytes. The stride value allows you to skip elements from the underlying buffer.

By default, the stride is set to the size of the type of slice in bytes. This means that the slice represents a contiguous memory range. If you don't need a stride and are only working with contiguous memory ranges, use [NativeArray\<T>](/engine/6000.7/script-reference/unity/collections/nativearray1.md) instead.
