type ProcessGroup struct {
	// contains filtered or unexported fields
}

ProcessGroup is an errgroup that listens for OS process signals

func NewProcessGroup(outerCtx context.Context) *ProcessGroup

NewProcessGroup creates a new ProcessGroup

func (pg *ProcessGroup) Context() context.Context

Context returns the context used by the ProcessGroup

func (pg *ProcessGroup) Go(f func() error)

Go calls the given function in a new goroutine.

The first call to return a non-nil error cancels the group; its error will be returned by Wait.

func (pg *ProcessGroup) Start(f func(context.Context) error)

Start calls the given function in a new goroutine and passes this group's context to it.

The first call to return a non-nil error cancels the group; its error will be returned by Wait.

func (pg *ProcessGroup) Wait() error

Wait blocks until all function calls from the Go method have returned, then returns the first non-nil error (if any) from them.
