Enum Event 

#[non_exhaustive]
pub enum Event {
    Start,
    HeartBeat,
    Custom(Box<dyn Any + Send + Sync + 'static>),
    Success(Box<dyn Any + Send + Sync + 'static>),
    Error(Arc<BoxDynError>),
    Stop,
    Exit,
}

Events emitted by a worker

Variants (Non-exhaustive)

Non-exhaustive enums could have additional variants added in future. Therefore, when matching against variants of non-exhaustive enums, an extra wildcard arm must be added to account for any future variants.

Start

Worker started

HeartBeat

Worker did a heartbeat

Custom(Box<dyn Any + Send + Sync + 'static>)

A custom event

Success(Box<dyn Any + Send + Sync + 'static>)

A result of processing

Error(Arc<BoxDynError>)

Error encountered during processing, would not stop the worker, but would be logged and sent to the event handler

Stop

Worker stopped

Exit

Worker exited, no further processing
