  * `doc` contains the description of the crate.
  *
  * `p` is a list of path/type pairs. It is used for parents and function parameters.
+ * The first item is the type, the second is the name, the third is the visible path (if any) and
+ * the fourth is the canonical path used for deduplication (if any).
+ *
+ * `r` is the canonical path used for deduplication of re-exported items.
+ * It is not used for associated items like methods (that's the fourth element
+ * of `p`) but is used for modules items like free functions.
  *
  * `c` is an array of item indices that are deprecated.
