## wiring.validate_quarantine_key()


Raise if another asset already materializes the quarantine's asset key.


Usage

``` python
wiring.validate_quarantine_key(context)
```


Call it at the start of a hand-wired asset's function when the asset writes a quarantine, as `dd.asset` does. In a direct invocation it does nothing.


## Raises


`QuarantineKeyCollisionError`  
Another asset in the code location materializes `<name>_quarantine`.
