English

Returns:;; A boolean indicating whether or not there is an element with key equal to `k` in the table. Notes:;; The `template<class K>` overload only participates 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. + + In the presence of concurrent insertion operations, the value returned may not accurately reflect the true state of the table right after execution.

	Chinese (Simplified Han script) 返回值：;; 与键 `k` 等价的元素数量（值为 0 或 1）。注意：;; 仅当 `Hash::is_transparent` 和 `Pred::is_transparent` 是有效的成员类型别名时，`template<class k="">` 重载版本才参与重载决议。库假定 `Hash` 可同时接受 `K` 类型与 `Key` 类型作为参数，且 `Pred` 是透明的。这支持异构查找，从而避免实例化 `Key` 类型对象带来的性能开销。在存在并发插入操作的情况下，返回的值可能无法精确反映执行后容器的真实状态。</class> 269/5900 · 590 Needs editing
