Return an iterator providing non‐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.
