Open-addressing and concurrent containers can be configured to keep running statistics of some internal operations affected by the quality of the supplied hash function.
Provides the number of insertion operations performed by a container and statistics on the associated __probe length__ (number of xref:structures.adoc#structures_open_addressing_containers[bucket groups] accessed per operation).
For successful (element found) or unsuccessful (not found) lookup, provides the number of operations performed by a container and statistics on the associated __probe length__ (number of xref:structures.adoc#structures_open_addressing_containers[bucket groups] accessed) and number of element comparisons per operation.
These statistics can be used to determine if a given hash function can be marked as link:../../../../../container_hash/doc/html/hash.html#ref_hash_is_avalanchinghash[__avalanching__].
