Remarks
Launches a task for asynchronous execution, with prerequisites that must be completed before the task is scheduled a trivially relocatable instance that can be used to wait for task completion or to obtain task execution result
Parameters
| Name | Description |
|---|---|
| DebugName | a unique name for task identification in debugger and profiler, is compiled out in test/shipping builds |
| TaskBody | a functor that will be executed asynchronously |
| Prerequisites | tasks or task events that must be completed before the task being launched can be scheduled, accepts any iterable collection (.begin()/.end()), Tasks::Prerequisites() helper is recommended to create such collection on the fly |
| Priority | task priority that affects when the task will be executed |
