Types

type Option

type Option func(*manager) error

Option represents a function that helps to configure the manager

func WithDefaultHandler

func WithDefaultHandler(processID common.ProcessID) Option

WithDefaultHandler option includes a default handler for the specified process id

func WithtHandler

func WithtHandler(h *handler) Option

WithtHandler option allows to reuse previously defined handlers
