Declared in `<bslstl_unorderedset.h>`

Return an iterator providing modifiable access to the `value_type` object in this unordered set that is equivalent to the specified `key`, if such an entry exists, and the past‐the‐end (`end`) iterator otherwise.

Return an iterator providing modifiable access to the `value_type` object in this unordered set that is equivalent to the specified `key`, if such an entry exists, and the past‐the‐end (`end`) iterator otherwise. The behavior is undefined unless `key` is equivalent to at most one element in this unordered set.
