Types

type Runner

type Runner interface {
	Run(func() error)
	Wait() error
}

Runner wraps the lifecycle methods of a new task set.

Run will block until a worker is available or the context is cancelled, and then run the given func in a new goroutine. Wait will wait for all the running goroutines to finish.

type Workers

	// contains filtered or unexported fields
}

Workers configures a task executor with the most number of tasks to be executed in parallel.

func New

func New(numWorkers int) *Workers

New creates a new Workers with the given number of workers.

func (*Workers) Start

func (w *Workers) Start(ctx context.Context) (Runner, context.Context)

Start starts a new Runner.
