Run is a record createId when a run of a task is scheduled.
type RunFilter ¶
type RunFilter struct { // Task ID is required for listing runs. Task platform.ID After *platform.ID Limit int AfterTime string BeforeTime string }
RunFilter represents a set of filters that restrict the returned results
type Task ¶

Task is a task. 🎊
func (*Task) EffectiveCron ¶
EffectiveCron returns the effective cron string of the options. If the cron option was specified, it is returned. If the every option was specified, it is converted into a cron string using "@every". Otherwise, the empty string is returned. The value of the offset option is not considered.
type TaskCreate ¶
type TaskCreate struct { Content string `json:"content"` // 内容 Path string `json:"path"` // 内容 Symbol string `json:"symbol"` // 标签 Interval string `json:"interval"` // 标签 Type string `json:"type,omitempty"` Flux string `json:"flux"` Description string `json:"description,omitempty"` Status string `json:"status,omitempty"` OrganizationID platform.ID `json:"orgID,omitempty"` Organization string `json:"org,omitempty"` OwnerID platform.ID `json:"-"` Metadata map[string]interface{} `json:"-"` // not to be set through a web request but rather used by a http service using tasks backend. }
TaskCreate is the set of values to create a task.
