Detailed Description

Priority-based task scheduler.

This header defines a small, thread-based scheduler that executes tasks in priority order. A lower numeric priority is executed before a higher numeric priority (min-heap behavior). Tasks return a value of type Y, and callers can wait on results via std::future<Y>.

This is implemented as a policy specialization of gtsam::Scheduler.

Example

gtsam::PriorityScheduler<int> scheduler(4);
auto future = scheduler.schedule(0, [] { return 42; });
int value = future.get();
