English

Returns:;; The number of elements with key equivalent to `k` (0 or 1). 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：匹配键 `k` 的元素数量（0 或 1）。说明：仅当 `Hash::is_transparent` 和 `Pred::is_transparent` 为有效成员类型别名时，`template<class k="">` 重载版本才参与重载决议。库假定哈希函数可同时作用于 `K` 类型与键类型，且相等谓词是透明的，从而支持异构查找，避免实例化键类型带来的开销。若存在并发插入操作，返回值可能无法精确反映容器执行后的真实状态。</class> 226/5900 · 590 Needs editing
