reduce memory overhead by storing indices (u8) in the queues instead of pointers (*mut u8) in the binary heap we store the baseline inline along with the index and the task name. Before we stored a pointer to the message and had to lookup the baseline when comparing two nodes in the heap. 2018-05-04 10:59:23 +02:00			`pub baseline: Instant,`
