Outdated
There was a problem hiding this comment.
I have to manually merge the result of tcx.explicit_item_bounds and tcx.explicit_predicates_of even though there is a query that already does both, namely tcx.trait_explicit_predicates_and_bounds. However, the latter only works for local definitions (and therefore only accepts LocalDefIds) and we obviously need to be able to handle cross-crate definitions.

Alternatively, I can remove the bound re-sugaring and only keep the type Out14<P, Q>
where
P: Copy + Eq,
Q: ?SizedThis would be similar to what we currently do for (cross-crate) trait parameters. E.g. In any case, as far as I know (and as far as the existing comments vaguely state) there truly is no means to get to know if the user actually wrote the bounds in the where-clause or directly attached to the parameters since this seems to be lost when desugaring, when storing the crate metadata and/or when the data is cleaned. I am not sure which one is the case. Maybe we can reconstruct this piece of information by looking at the spans (if available). No idea. Just note that this is a well-known shortcoming of rustdoc's cross-crate documentation abilities. Confer several A-cross-crate-reexports issues. |

Apart from my question, looks all good to me, thanks! |
