Constants ¶
const (
// TypeAsync - type async
TypeAsync = "async"
)
const (
// TypeAsyncWorker - type async worker
TypeAsyncWorker = "async_worker"
)
Variables ¶
var ErrNotImpl = errors.New("method not impl")
ErrNotImpl - error for not impl
Functions ¶
func Register ¶
Register makes a Task adapter available by the adapter name. If Register is called twice with the same name or if driver is nil, it panics.
func RegisterWorker ¶
func RegisterWorker(name string, adapter WorkerInstance)
RegisterWorker makes a Task worker adapter available by the adapter name. If Register is called twice with the same name or if driver is nil,
Types ¶
type Arg ¶
type Arg struct {
Name string `json:"name"`
Type string `json:"type"`
Value interface{} `json:"value"`
}
Arg represents a single argument passed to invocation fo a task
type CallbackFunc ¶
CallbackFunc - task call back function
type Config ¶
type Config struct {
// async task

Logger log.Logger `json:"logger"`
ErrorHandler func(err error)
PreTaskHandler func(param *Param)
PostTaskHandler func(param *Param)
// Extend fields
// Extended fields can be used if there is a special implementation
Extend1 string `json:"extend_1"`
Extend2 string `json:"extend_2"`
}
Config - task config
type FuncWrap ¶
type FuncWrap interface {
// get all task func
GetTasks() map[string]interface{}
// stop task by uuid
StopTask(uuid string) error
}
FuncWrap - task worker func warp

UUID string `json:"uuid"`
Name string `json:"name"`
Fun string `json:"fun"`
Option Option `json:"option"`
Args []Arg `json:"args"`
WaitTimeOut time.Duration `json:"wait_time_out"`
}
Param task param
type ParamFromContext ¶
ParamFromContext - convert context value to Param
var ParamFunc ParamFromContext
ParamFunc - point ParamFromContext impl
type Result ¶
type Result interface {
// Get - get result with sleep
Get(sleepDuration time.Duration) ([]reflect.Value, error)
// GetWithTimeout - get with timeout
GetWithTimeout(timeoutDuration, sleepDuration time.Duration) ([]reflect.Value, error)
}
Result - task result value
type Task ¶
type Task interface {
// add new task
AddTask(param *Param, onSuccess []*Param, onError []*Param, callbacks ...CallbackFunc) error
// run all task
// if chain is true, The tasks will be executed in turn, and the return value of the previous
// task will be used as the parameter of the next task
Run(chain bool) error
// stop all task
Stop() error
// start gc routine based on config settings.
StartAndGC(config Config) error
}
Task interface contains all behaviors for Task adapter.
type Worker ¶
type Worker interface {
// run worker
Run() error
// close worker
Close() error
// start gc routine based on config string settings.
StartAndGC(config Config) error
}
Worker interface contains all behaviors for task worker
type WorkerInstance ¶
type WorkerInstance func() Worker
WorkerInstance is a function create a new Task worker Instance
