sdk::metrics::AdaptingIntegerArray Class Reference

Detailed Description

An integer array that automatically expands its memory consumption (via copy/allocation) when reaching limits.

This assumes counts remain low, to lower memory overhead.

This class is NOT thread-safe. It is expected to be behind a synchronized incrementer.

Instances start by attempting to store one-byte per-cell in the integer array. As values grow, this will automatically instantiate the next-size integer array (uint8_t -> uint16_t -> uint32_t -> uint64_t) and copy over values into the larger array. This class expects most usage to remain within the uint8_t boundary (e.g. cell values < 256).
