:mrdocs:

Insert into this hash map elements having the key‐value pairs obtained between the specified `first` (inclusive) and `last` (exclusive) random‐access iterators. The iterators provide read access to a sequence of `bsl::pair<KEY, VALUE>` objects. If an element having one of the keys already exists in this hash map, set the value attribute to the corresponding value from `data`. All insertions are done by the calling thread and the order of insertion is not specified. Return the number of elements inserted. The behavior is undefined unless `first <= last`.
