What works and what does not (21st March 2020 11:22 AM)
|
|
|
|
- Run tasks concurrently: V
|
|
- Join mechanism: V
|
|
- Sleep mechanism: V
|
|
- Cancellation mechanism: V
|
|
- Exception propagation: V
|
|
- Concurrent I/O: X Note: I/O would work only when a task is joined (weird)
|
|
- Return values of coroutines: X Note: Return values ARE actually stored in task objects properly, but are messed up later when joining tasks
|
|
- Scheduling tasks for future execution: V
