Remarks

Exceptions that are not caught by this helper will bubble up to the caller of run. This ensures that known exceptions can be handled within the flow context.

Parameters

• handler: A function of type exn -> 'error to map the exception.
• flow: The source flow of type Flow to monitor.

Returns

A Flow that converts exceptions into success-path errors.
