Some initial normalization method changes #104905

compiler-errors · 2022-11-25T18:24:35Z

Rename AtExt::normalize to QueryNormalizeExt::query_normalize (using the QueryNormalizer)
Introduce NormalizeExt::normalize to replace partially_normalize_associated_types_in (using the AssocTypeNormalizer)
Rename FnCtxt::normalize_associated_types_in to FnCtxt::normalize
Remove some unused other normalization fns in Inherited and FnCtxt

Also includes one drive-by where we're no longer creating a FnCtxt inside of check_fn, but passing it in. This means we don't need such weird FnCtxt construction logic.

Stacked on top of #104835 for convenience.

        debug!(
            "instantiate_bounds(bounds={:?}, substs={:?}) = {:?}, {:?}",
            bounds, substs, result, spans,
        );
        (result, spans)
    }

-    pub(in super::super) fn normalize_associated_types_in<T>(&self, span: Span, value: T) -> T
+    pub(in super::super) fn normalize<T>(&self, span: Span, value: T) -> T


This intentionally takes a span instead of an ObligationCause because all of FnCtxt::normalize callers would be creating misc causes.

-                fn_sig,

+            // FIXME(compiler-errors): Remove


Should have been fixed in the next commit

general notes:

we should probably remove struct Normalized and always use InferOk
we have to add/update the comments for the normalization routines
remove normalize_to and normalize in favor of normalize_with_depth_to and normalize_with_depth

apart from that r=me

thanks ❤️
