### Remarks

Allows a buffer to be treated like a stack in compute shaders. Maps to `AppendStructuredBuffer<T>` or `ConsumeStructuredBuffer<T>` in HLSL.

When you construct a GraphicsBuffer of this type, the value of `stride` must match the stride of the corresponding StructuredBuffer struct type in your HLSL code. It must also be a multiple of 4, and less than 2048.

See Microsoft's HLSL documentation on [AppendStructuredBuffer](https://docs.microsoft.com/en-us/windows/win32/direct3dhlsl/sm5-object-appendstructuredbuffer) and [ConsumeStructuredBuffer](https://docs.microsoft.com/en-us/windows/win32/direct3dhlsl/sm5-object-consumestructuredbuffer).

The buffer size value can be copied into another buffer using [GraphicsBuffer.CopyCount](/engine/6000.7/script-reference/unityengine/graphicsbuffer/copycount.md), or explicitly reset with [GraphicsBuffer.SetCounterValue](/engine/6000.7/script-reference/unityengine/graphicsbuffer/setcountervalue.md).
