	English Requires:;; `value_type` is https://en.cppreference.com/w/cpp/named_req/EmplaceConstructible[EmplaceConstructible^] from `k`. Returns:;; `true` if an insert took place. Concurrency:;; Blocking on rehashing of `*this`. Notes:;; These overloads only participate in overload resolution if `Hash::is_transparent` and `Pred::is_transparent` are valid member typedefs. The library assumes that `Hash` is callable with both `K` and `Key` and that `Pred` is transparent. This enables heterogeneous lookup which avoids the cost of instantiating an instance of the `Key` type.
	Chinese (Simplified Han script) ↹ ↵ NBS … 「 」 『 』 ﹙-﹚ ‐ – — 要求：;; `value_type` 可基于 `k` 满足 https://en.cppreference.com/w/cpp/named_req/EmplaceConstructible[EmplaceConstructible^]。 返回值：;; 插入成功则返回 `true`。 并发特性：;; 会阻塞 `*this` 的重哈希操作。 注意：;; 仅当 `Hash::is_transparent` 与 `Pred::is_transparent` 为合法成员类型别名时，此类重载函数才参与重载决议。本库假定 `Hash` 可接收 `K` 与 `Key` 两种类型进行调用，且 `Pred` 具备透明特性。该特性支持异构查找，省去了实例化 `Key` 类型对象的开销。 336/5660 · 566 Needs editing
