# timeout

An error code that indicates the system interrupted and terminated the command buffer before it finished running.

## Declaration

```swift
static var timeout: MTLCommandBufferError.Code { get }
```

## Discussion

Discussion Possible causes include: The commands in the buffer took more time to run than the system allows. The command buffer timed out waiting for another workload to signal an MTLEvent.
