Types ¶
type Queue ¶
type Queue interface {
Start(ctx context.Context) (<-chan error, error)
Push(ctx context.Context, job JobFunc) error
Pop(ctx context.Context) (JobFunc, error)
Len() uint64
}
Queue represents the interface of queue.
func NewQueue ¶
func NewQueue(opts ...QueueOption) (Queue, error)
NewQueue returns Queue if no error is occurred.
func NewQueueMock ¶ added in v1.0.5
func NewQueueMock() Queue
type QueueMock ¶ added in v1.0.5
type QueueMock struct {
StartFunc func(context.Context) (<-chan error, error)
PushFunc func(context.Context, JobFunc) error
PopFunc func(context.Context) (JobFunc, error)
LenFunc func() uint64
}
type QueueOption ¶
type QueueOption func(q *queue) error
QueueOption represents the functional option for queue.
func WithQueueBuffer ¶

TotalCompleted() uint64
Dispatch(ctx context.Context, f JobFunc) error
}
Worker represents the worker interface to execute jobs.
func New ¶
func New(opts ...WorkerOption) (Worker, error)
New initializes and return the worker, or return initialization error if occurred.
