# Type Alias: ExternalSubmissionContext

> **ExternalSubmissionContext** = `ResourceUnwrapContext`

Defined in: [packages/webgpu/src/types.ts:664](https://github.com/uinosoft/zenfg/blob/327c05c78d2f528e4f4a679fcc7a77d9aa161f48/packages/webgpu/src/types.ts#L664)

**`Beta`**

Context passed to an opaque caller-owned queue submission callback.

It provides no FrameGraph-owned command encoder. The callback must enqueue all
graph-visible work on this device's queue before returning, must not retain
resolved transient resources, and must not recursively execute, clear, or
destroy the same FrameGraph runtime. Queue submission does not imply GPU
completion.
