Restructure hir::map::Node and hir::map::Entry#53616

varkor · 2018-08-22T21:26:04Z

Moves hir::map::Node to hir::Node and removes the Node* prefix from its variants.
Changes hir::map::Entry to a struct hir::map::Entry.
Removes the Node* prefix from each of AnnNodes variants.

Entry being an enum is a dead optimization FWIW (because of DepNodeIndex), what you want is this:

struct Entry {
    parent: NodeId,
    dep_node: DepNodeIndex,
    node: Node,
}

Add RootCrate to Node as just Crate, then NotPresent is replaced by having Option<Entry> (which nowadays should be the same size as Entry).

Also, since Node isn't a struct, you can just have e.g. Node::Expr which is IMO nicer.
Oh and you can move Node to hir, keep only Entry in hir::map.

varkor · 2018-08-25T18:41:51Z

All done!

I think you actually want CRATE_NODE_ID here.

I don't think this is useful.

I don't think this is super relevant. Also, we could technically make this point to data as well, it'd just not be cleanly separated yet, so we can't do it (would break incremental).

@eddyb: well, it didn't like those changes. I guess excluding the crate root was important.
