Usage

• Add Tusk.DynamicSupervisor to your supervision tree
• Tusk.run(sup, task, options)
  • where sup is the dynamic supervisor
  • task can be an {m, f, a} tuple or a closure (anonymous function)
• Available options
  • timeout: integer, :infinity or nil
    • both :infinity and nil disable timeout
  • callbacks:
    • on_success: mfa or closure
    • on_failure: mfa or closure
    • on_error: mfa or closure
    • on_success gets called with the task result
    • on_failure is called once after no more retries
    • on_error is called every time an error occurs
    • on_failure and on_error get called with an error
  • no_retry_exceptions:
    • a list of Exception names that if seen, give up retrying
