| * Each hash must be wrapped in a thin redirector conformant with the BMK_benchfn_t. |
| * BMK_benchfn_t is generic, not specifically designed for hashes. |
| * For hashes, the following parameters are expected to be useless: |
| * dst, dstCapacity, customPayload. |
| * |
| * The result of each hash is assumed to be provided as function return value. |
| * This condition is important for latency measurements. |
