Objective
The method
World::try_run_schedule
currently panics if theSchedules
resource does not exist, but it should just return anErr
. Similarly,World::add_schedule
panics unnecessarily if the resource does not exist.Also, the documentation for
World::add_schedule
is completely wrong.Solution
When the
Schedules
resource does not exist, we now treat it the same as if it did exist but was empty. When callingadd_schedule
, we initialize it if it does not exist.
