![]() First of all, note that `Map` has three different relevant meanings. - The `intravisit::Map` trait. - The `map::Map` struct. - The `NestedFilter::Map` associated type. The `intravisit::Map` trait is impl'd twice. - For `!`, where the methods are all unreachable. - For `map::Map`, which gets HIR stuff from the `TyCtxt`. As part of getting rid of `map::Map`, this commit changes `impl intravisit::Map for map::Map` to `impl intravisit::Map for TyCtxt`. It's fairly straightforward except various things are renamed, because the existing names would no longer have made sense. - `trait intravisit::Map` becomes `trait intravisit::HirTyCtxt`, so named because it gets some HIR stuff from a `TyCtxt`. - `NestedFilter::Map` assoc type becomes `NestedFilter::MaybeTyCtxt`, because it's always `!` or `TyCtxt`. - `Visitor::nested_visit_map` becomes `Visitor::maybe_tcx`. I deliberately made the new trait and associated type names different to avoid the old `type Map: Map` situation, which I found confusing. We now have `type MaybeTyCtxt: HirTyCtxt`. |
