	English Requires:;; `nh` is empty or `nh.get_allocator()` is equal to the container's allocator. Returns:;; If `nh` was empty, returns `end()`. + + Otherwise returns an iterator pointing to the newly inserted element. Throws:;; If an exception is thrown by an operation other than a call to hasher the function has no effect. Notes:;; The standard is fairly vague on the meaning of the hint. But the only practical way to use it, and the only way that Boost.Unordered supports is to point to an existing element with the same key. + + Can invalidate iterators, but only if the insert causes the load factor to be greater to or equal to the maximum load factor. + + Pointers and references to elements are never invalidated. + + This can be used to insert a node extracted from a compatible `unordered_set`. 798/10000 · 798

	English Returns:;; The iterator following `position` before the erasure. Throws:;; Only throws an exception if it is thrown by `hasher` or `key_equal`. Notes:;; In older versions this could be inefficient because it had to search through several buckets to find the position of the returned iterator. The data structure has been changed so that this is no longer the case, and the alternative erase methods have been deprecated. 420/10000 · 420

245 :954

	English Returns:;; The number of elements erased. Throws:;; Only throws an exception if it is thrown by `hasher` or `key_equal`. Notes:;; The `template<class K>` 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. 567/10000 · 567

	English Returns:;; The iterator following the erased elements - i.e. `last`. Throws:;; Only throws an exception if it is thrown by `hasher` or `key_equal`. + + In this implementation, this overload doesn't call either function object's methods so it is no throw, but this might not be true in other implementations. 307/10000 · 307
