Events

Event: 'error'

An 'error' event is emitted by instances of this class when:

• Uncaught exceptions occur inside Worker threads that do not currently handle tasks.
• Unexpected messages are sent from from Worker threads.

All other errors are reported by rejecting the Promise returned from run() or runTask(), including rejections reported by the handler function itself.

Event: 'drain'

A 'drain' event is emitted whenever the queueSize reaches 0.

Event: 'needsDrain'

Similar to Piscina#needsDrain; this event is triggered once the total capacity of the pool is exceeded by number of tasks enqueued that are pending of execution.

Event: 'message'

A 'message' event is emitted whenever a message is received from a worker thread.
