:mrdocs:

Insert the specified `link`, having the specified (non‐adjusted) `hashCode`, into the specified `anchor` immediately before the specified `position` in the bi‐directional linked list of `anchor`. The behavior is undefined unless position is in the bucket having index `computeBucketIndex(hashCode, anchor‐>bucketArraySize())` and `anchor` is well‐formed (see `isWellFormed`) for some combination of `KEY_CONFIG` and `HASHER` such that `link` refers to a node of type `BidirectionalNode<KEY_CONFIG::ValueType>` and `HASHER(extractKey<KEY_CONFIG>(link))` returns `hashCode`.
