	English	Chinese (Simplified Han script)	Actions
	In debug builds (more precisely, when link:../../../../../assert/doc/html/assert.html#boost_assert_is_void[`BOOST_ASSERT_IS_VOID`^] is not defined), __container reentrancies__ (illegaly invoking an operation on `m` from within a function visiting elements of `m`) are detected and signalled through `BOOST_ASSERT_MSG`. When run-time speed is a concern, the feature can be disabled by globally defining this macro.	在调试版本中（更准确地说，当未定义 link:../../../../../assert/doc/html/assert.html#boost_assert_is_void[`BOOST_ASSERT_IS_VOID`] 时），系统会检测__容器重入__行为（即在访问 `m` 元素的函数内部非法调用 `m` 上的操作），并通过 `BOOST_ASSERT_MSG` 发出信号。若需关注运行时速度，可通过全局定义此宏来禁用该功能。
	`BOOST_UNORDERED_ENABLE_STATS`	`BOOST_UNORDERED_ENABLE_STATS`
	Globally define this macro to enable xref:reference/stats.adoc#stats[statistics calculation] for the table. Note that this option decreases the overall performance of many operations.	全局定义此宏以启用容器的 xref:reference/stats.adoc#stats[统计计算] 功能。请注意，此选项会降低多数操作的总体性能。

	Constructs a table, copying ``other``'s contained elements, hash function, and predicate, but using allocator `a`.	构造一个表，复制other的容器元素、哈希函数和谓词，但使用分配器a。
	If `a == other.get_allocator()`, the elements of `other` are transferred directly to the new table; otherwise, elements are moved-constructed from those of `other`. The hash function and predicate are moved-constructed from `other`, and the allocator is copy-constructed from `a`. If statistics are xref:concurrent_flat_map_boost_unordered_enable_stats[enabled], transfers the internal statistical information from `other` iff `a == other.get_allocator()`, and always calls `other.reset_stats()`.	若a == other.get_allocator()，则other的元素会直接转移到新表中；否则，元素从other移动构造而来。哈希函数与谓词从other移动构造，分配器从a拷贝构造。如果启用了 xref:concurrent_flat_map_boost_unordered_enable_stats [统计功能]：当且仅当a == other.get_allocator()时，从other转移内部统计信息始终调用other.reset_stats()

	Move construction from a xref:#unordered_flat_map[`unordered_flat_map`]. The internal bucket array of `other` is transferred directly to the new container. The hash function, predicate and allocator are moved-constructed from `other`. If statistics are xref:concurrent_flat_map_boost_unordered_enable_stats[enabled], transfers the internal statistical information from `other` and calls `other.reset_stats()`.	从 xref:#unordered_flat_map [unordered_flat_map] 进行移动构造。other的内部桶数组会直接转移到新容器中。哈希函数、谓词和分配器均从other移动构造而来。如果启用了 xref:concurrent_flat_map_boost_unordered_enable_stats [统计功能]，则从other转移内部统计信息，并调用other.reset_stats()。
