	English Requires:;; `value_type` is https://en.cppreference.com/w/cpp/named_req/EmplaceConstructible[EmplaceConstructible^] from `k`. Returns:;; The bool component of the return type is true if an insert took place. + + If an insert took place, then the iterator points to the newly inserted element. Otherwise, it points to the element with equivalent key. Throws:;; If an exception is thrown by an operation other than a call to `hasher` the function has no effect. Notes:;; Can invalidate iterators, but only if the insert causes the load to be greater than the maximum load. + + This overload only participates in overload resolution if `Hash::is_transparent` and `Pred::is_transparent` are valid member typedefs and neither `iterator` nor `const_iterator` are implicitly convertible from `K`. 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` 可以从 `k` 进行 https://en.cppreference.com/w/cpp/named_req/EmplaceConstructible[可原位构造^]。 返回：如果发生了插入，则返回类型的 bool 分量为 true。 如果发生了插入，则迭代器指向新插入的元素；否则，指向具有等价键的元素。 抛出：如果除调用 `hasher` 之外的操作抛出异常，则该函数无效果。 注意：可能使迭代器失效，但仅当插入导致负载大于最大负载时才会发生。 只有当 `Hash::is_transparent` 和 `Pred::is_transparent` 是有效的成员 typedef，且 `iterator` 和 `const_iterator` 都不能从 `K` 隐式转换时，此重载才会参与重载决议。库假定 `Hash` 可同时用 `K` 和 `Key` 调用，并且 `Pred` 是透明的。这支持了异构查找，从而避免了实例化 `Key` 类型对象的开销。 456/9930 · 993 Needs editing

Returns:;; `true` if an insert took place. + Concurrency:;; Blocking on rehashing of `*this`. Notes:;; Invalidates pointers and references to elements if a rehashing is issued. + + A call of the form `insert(x)`, where `x` is equally convertible to both `const value_type&` and `const init_type&`, is not ambiguous and selects the `init_type` overload.
