# Type Alias: BufferDesc

> **BufferDesc** = `object`

Defined in: [packages/webgpu/src/types.ts:380](https://github.com/uinosoft/zenfg/blob/327c05c78d2f528e4f4a679fcc7a77d9aa161f48/packages/webgpu/src/types.ts#L380)

**`Beta`**

Describes a transient buffer allocated and recycled by FrameGraph.

FrameGraph takes a shallow snapshot for the current recording. When `usage`
is omitted, required usage is derived from retained node accesses.
