r=me after nit for everything outside of df90ba0 I personally don't think reflowing comments is worth it as it results in merge conflicts for little benefit, e.g. the changes to
will conflict with #135899. |
|
☔ The latest upstream changes (presumably #134824) made this pull request unmergeable. Please resolve the merge conflicts. |
I was confused here for a bit.
Also rewrite the merged arm slightly to more closely match the arm above it.
This comment made sense when this crate was called `rustc_typeck`, but makes less sense now that it's called `rustc_hir_analysis`. Especially given that `check_drop_impl` is only called within the crate.
Note: `inherit_predicates_for_delegation_item` already has these cases merged.
There is a comment `Delegation to inherent methods is not yet supported.` that appears three times mid-pattern and somehow inhibits rustfmt from formatting the enclosing `match` statement. This commit moves them to the top of the pattern, which enables more formatting.
`delegation.rs` has three builders: `GenericsBuilder`, `PredicatesBuilder`, and `GenericArgsBuilder`. The first two builders have just two optional parameters, and the third one has zero. Each builder is used within a single function. The code is over-engineered. This commit removes the builders, replacing each with with a single `build_*` function. This makes the code shorter and simpler.
It used to be bigger, with an `Xform` trait, but now it has just a single function.

Instead re-export `rustc_hir_analysis::collect::suggest_impl_trait`, which is the only thing from the module used in another crate. This fixes a `FIXME` comment. Also adjust some visibilities to satisfy the `unreachable_pub` lint. This changes requires downgrading a link in a comment on `FnCtxt` because `collect` is no longer public and rustdoc complains otherwise. This is annoying but I can't see how to avoid it.
