For example, if you have a [`DefId`], and you would like to convert it
to a [`NodeId`], you can use [`tcx.hir.as_local_node_id(def_id)`][as_local_node_id]. This
returns an `Option<NodeId>` – this will be `None` if the def-id
refers to something outside of the current crate (since then it has no
HIR node), but otherwise returns `Some(n)` where `n` is the node-id of
the definition.
