Update Clippy #102729

It allows using `LocalDefId` instead of `DefId` when possible, and also encode cheaper `Visibility<DefIndex>` into metadata.

This shrinks `hir::Ty` from 72 to 48 bytes. `visit_lifetime` is added to the HIR stats collector because these types are now stored in memory on their own, instead of being within other types.

This shrinks `hir::Pat` from 88 to 72 bytes.

Allow lint passes to be bound by `TyCtxt` This will allow storing things like `Ty<'tcx>` inside late lint passes. It's already possible to store various id types so they're already implicitly bound to a specific `TyCtxt`. r? rust-lang/compiler

Initial implementation of dyn* This PR adds extremely basic and incomplete support for [dyn*](https://smallcultfollowing.com/babysteps//blog/2022/03/29/dyn-can-we-make-dyn-sized/). The goal is to get something in tree behind a flag to make collaboration easier, and also to make sure the implementation so far is not unreasonable. This PR does quite a few things: * Introduce `dyn_star` feature flag * Adds parsing for `dyn* Trait` types * Defines `dyn* Trait` as a sized type * Adds support for explicit casts, like `42usize as dyn* Debug` * Including const evaluation of such casts * Adds codegen for drop glue so things are cleaned up properly when a `dyn* Trait` object goes out of scope * Adds codegen for method calls, at least for methods that take `&self` Quite a bit is still missing, but this gives us a starting point. Note that this is never intended to become stable surface syntax for Rust, but rather `dyn*` is planned to be used as an implementation detail for async functions in dyn traits. Joint work with `@nikomatsakis` and `@compiler-errors.` r? `@bjorn3`

Clippy pre beta branch fix Before beta is branched on Friday, I want to move the `unused_peekable` lint that was added in this release cycle (1.65) to `nursery`. This lint was already reported twice (rust-lang/rust-clippy#9456, rust-lang/rust-clippy#9462) in a short time, so it is probably a good idea to fix it before it hits beta and then stable. r? `@Manishearth`

nyurik · 2022-10-06T14:55:21Z

Because Rust CI enables debug stuff like overflow checking. In Clippy we use a release compiled rustc.

@flip1995 can we add a debug build of rustc to clippy CI?

flip1995 · 2022-10-06T15:30:34Z

As rarely as things break in debug mode (about 1-2x a year), it wouldn't be worth the effort.

nyurik · 2022-10-06T15:41:02Z

I guess as long as it gets caught before being sent to the users, its ok

flip1995 · 2022-10-06T15:44:16Z

@Manishearth Now it is resynced. Tests pass locally, however I did not test with debug, so maybe we should wait on CI before approving.
