func Start[T any](ctx context.Context, logger Logger, processors ...Processor[T]) (<-chan T, <-chan error)

Start manages worker goroutines to process items in provided channels. If logger is nil, it defaults to NoOpLogger.

type Logger interface {
	Info(msg string, keysAndValues ...interface{})
	Error(msg string, keysAndValues ...interface{})
}

Logger interface that all loggers must implement

type NoOpLogger struct{}

NoOpLogger default logger that does nothing

func (n *NoOpLogger) Error(msg string, keysAndValues ...interface{})

func (n *NoOpLogger) Info(msg string, keysAndValues ...interface{})

type Processor[T any] struct {
	ProcessFunc func(T) (T, error)
	Chans       []<-chan T
}

Processor is a structure holding processing function and associated channels.

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

ZapLoggerAdapter adapts a zap.Logger to our Logger interface.

func NewZapLoggerAdapter(z *zap.Logger) *ZapLoggerAdapter

func (z *ZapLoggerAdapter) Error(msg string, keysAndValues ...interface{})

func (z *ZapLoggerAdapter) Info(msg string, keysAndValues ...interface{})
