The first one may be useful with hashing to put byte strings in
partitioning buckets for scaling. For example, to divide a dataset
into 32 partitions, hash the key then use toIndex(32) to map the
key to its partition.
The second one may be useful with dynamic experiments and A/B
tests. For example, to assign a control group to 5% of customers
hash the customer key then check if toFraction() is less than 0.05.
