Destroys previously existing elements, swaps the hash function and predicate from `other`, and move-assigns the allocator from `other` if `Alloc::propagate_on_container_move_assignment` exists and `Alloc::propagate_on_container_move_assignment::value` is `true`. If at this point the allocator is equal to `other.get_allocator()`, the internal bucket array of `other` is transferred directly to the new container; otherwise, inserts move-constructed copies of the elements of `other`. If statistics are xref:unordered_flat_map_boost_unordered_enable_stats[enabled], transfers the internal statistical information from `other` iff the final allocator is equal to `other.get_allocator()`, and always calls `other.reset_stats()`.
```c++ unordered_flat_map&amp; operator=(unordered_flat_map&amp;&amp; other) noexcept((boost::allocator_traits<allocator>::is_always_equal::value || boost::allocator_traits<allocator>::propagate_on_container_move_assignment::value) &amp;&amp; std::is_same<pointer, value_type*="">::value); ``` 移动赋值运算符。销毁之前存在的元素，交换 other 中的哈希函数和谓词，若 Alloc::propagate_on_container_move_assignment 存在且 Alloc::propagate_on_container_move_assignment::value 为 true，则从 other 移动赋值分配器。若此时分配器与 other.get_allocator() 相等，则将 other 的内部桶数组直接转移至当前容器；否则，插入通过移动构造从 other 元素创建的副本。若统计功能已启用（参见 xref:unordered_flat_map_boost_unordered_enable_stats[相关说明]），则仅当最终分配器与 other.get_allocator() 相等时转移 other 的内部统计信息，且始终会调用 other.reset_stats()。</pointer,></allocator></allocator>

The `template<class K, class\... Args>` overload only participates in overload resolution if `Hash::is_transparent` and `Pred::is_transparent` are valid member typedefs and neither `iterator` nor `const_iterator` are implicitly convertible from `K`. 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.

The `template<class K, class\... Args>` overload only participates in overload resolution if `Hash::is_transparent` and `Pred::is_transparent` are valid member typedefs and neither `iterator` nor `const_iterator` are implicitly convertible from `K`. 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.
