	English If `Allocator::propagate_on_container_swap` is declared and `Allocator::propagate_on_container_swap::value` is `true` then the containers' allocators are swapped. Otherwise, swapping with unequal allocators results in undefined behavior.

	English Effects:;; `x.swap(y)` Throws:;; Doesn't throw an exception unless it is thrown by the copy constructor or copy assignment operator of `key_equal` or `hasher`. Notes:;; The exception specifications aren't quite the same as the C++11 standard, as the equality predicate and hash function are swapped using their copy constructors.
	Chinese (Simplified Han script) ↹ ↵ NBS … 「 」 『 』 ﹙-﹚ ‐ – — 效果：`x.swap(y)` 抛出：除非 `key_equal` 或 `hasher` 的复制构造函数或复制赋值运算符抛出异常，否则不会抛出异常。 注意：由于相等谓词和哈希函数是通过它们的复制构造函数进行交换的，因此异常规范与 C++11 标准并不完全相同。 131/3290 · 329 Needs editing
