# Enumeration: BufferAccess

Defined in: [packages/webgpu/src/types.ts:36](https://github.com/uinosoft/zenfg/blob/327c05c78d2f528e4f4a679fcc7a77d9aa161f48/packages/webgpu/src/types.ts#L36)

**`Beta`**

Declares how a graph node uses a buffer.

FrameGraph derives read/write ordering and required `GPUBufferUsage` flags
from these values. Read-write use is expressed as separate access entries.

## Enumeration Members

### CopyDst

> **CopyDst**: `"buffer-copy-dst"`

Defined in: [packages/webgpu/src/types.ts:52](https://github.com/uinosoft/zenfg/blob/327c05c78d2f528e4f4a679fcc7a77d9aa161f48/packages/webgpu/src/types.ts#L52)

**`Beta`**

Uses the buffer as the destination of a copy or clear operation.

***
