	English The container visualizations also work if you are using fancy pointers in your allocator, such as `boost::interprocess::offset_ptr`. While this is rare, Boost.Unordered has natvis customization points to support any type of fancy pointer. `boost::interprocess::offset_ptr` has support already defined in the Boost.Interprocess library, and you can add support to your own type by following the instructions contained in a comment near the end of the file link:https://github.com/boostorg/unordered/blob/develop/extra/boost_unordered.natvis[/extra/boost_unordered.natvis].

	English Note that in this last example the visitation function could actually _modify_ the element: as a general rule, operations on a concurrent map `m` will grant visitation functions const/non-const access to the element depending on whether `m` is const/non-const. Const access can be always be explicitly requested by using `cvisit` overloads (for instance, `insert_or_cvisit`) and may result in higher parallelization. For concurrent sets, on the other hand, visitation is always const access.
	Chinese (Simplified Han script) ↹ ↵ NBS … 「 」 『 』 ﹙-﹚ ‐ – — 注意此例中访问函数可__修改__元素：作为通用规则，对并发映射 `m` 的操作将根据 `m` 是否为常量类型，授予访问函数对元素的常量/非常量访问权限。 通过使用 `cvisit` 重载（如 `insert++_++or++_++cvisit` ）可始终显式请求常量访问，这可能提升并行性。而并发集合的访问始终为常量访问。 161/4920 · 492 Needs editing

	English In practice, the extra indirection can have a dramatic performance impact to common operations such as `insert`, `find` and `erase`. But to keep iteration of the container fast, Boost.Unordered introduces a novel data structure, a "bucket group". A bucket group is a fixed-width view of a subsection of the buckets array. It contains a bitmask (a `std::size_t`) which it uses to track occupancy of buckets and contains two pointers so that it can form a doubly-linked list with non-empty groups. An example diagram is below:
