package needle_map
/* CompactMap is an in-memory map of needle indeces, optimized for memory usage.
*
* It's implemented as a map of sorted indeces segments, which are in turn accessed through binary
* search. This guarantees a best-case scenario (ordered inserts/updates) of O(N) and a worst case
* scenario of O(log n) runtime, with memory usage unaffected by insert ordering.
*
* Note that even at O(log n), the clock time for both reads and writes is very low, so CompactMap
* will seldom bottleneck index operations.
