English

Returns:;; An iterator pointing to an element with key equivalent to `k`, or `b.end()` if no such element exists. Notes:;; The templated overloads containing `CompatibleKey`, `CompatibleHash` and `CompatiblePredicate` are non-standard extensions which allow you to use a compatible hash function and equality predicate for a key of a different type in order to avoid an expensive type cast. In general, its use is not encouraged and instead the `K` member function templates should be used. + + The `template<class K>` 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) 返回：;; 指向键与 `k` 等价之元素的迭代器；若无此元素，则返回 `b.end()`。备注：;; 包含 `CompatibleKey`、`CompatibleHash` 和 `CompatiblePredicate` 的模板重载属于非标准扩展，允许使用兼容的哈希函数和相等谓词来处理不同类型的键，从而避免昂贵的类型转换。通常不建议使用它们，而应使用 `K` 成员函数模板。此外，仅当 `Hash::is_transparent` 和 `Pred::is_transparent` 是有效的成员 typedef 时，`template<class k="">` 重载才会参与重载决议。库假定 `Hash` 可同时以 `K` 和 `Key` 类型调用，且 `Pred` 是透明的。这支持了异构查找，从而避免了实例化 `Key` 类型的开销。</class> 380/8520 · 852 Needs editing
