Functions

func LoadStateCount 

func LoadStateCount(dbp zesty.DBProvider, tags map[string]string) (sc map[string]float64, err error)

func RegisterTaskTime added in v1.10.0 

func RegisterTaskTime(templateName string, taskCreation, resCreation time.Time)

Task is the full representation of a requested process on µTask A task is necessarily derived from a template, the formal description of the process to be executed, plus inputs provided by the requester The execution of the task will be handled through another structure, its resolution When the resolution is finalized, results will be committed back to the Task structure Comments can be added to a task, by all parties involved (requester and resolver) A task can be made visible to third parties by adding their usernames to the watcher_usernames list
