Update Rust toolchain version?

[EFanZh]

Description

Currently, Clippy is not able to be compiled with the latest Rust toolchain (For example: nightly-2023-09-10) due to API change, I think we may need to merge changes from rust-lang/rust@f49382c into this repository. Now I can help submit a PR, but I am not sure if there is a specific workflow for synchronizing commits between these two repositories (For example: keeping commit authors, dates, etc).

Version

rustc 1.74.0-nightly (8ed4537d7 2023-09-09)
binary: rustc
commit-hash: 8ed4537d7c238eb77509d82445cf1cb861a3b5ff

It gets synced every couple weeks, the process is documented here. The nightly will be updated after rust-lang/rust#115790 is completed

If you're looking to compile clippy with the current nightly you can do that from the main rust repo, src/tools/clippy is the code that's built for public installation, this repo is to aid the development of Clippy

I am using the clippy_utils crate for developing dylint programs. I need to add the clippy_utils that matches the toolchain I am using (currently nightly-2023-09-10) to my Cargo.toml as a lib dependency. I can’t add this dependency from the rust repository because the repository is too big, so I have to use a version from the rust-clippy repository.

Hey, @EFanZh. Sorry to hijack your issue, but this sounds like more of a Dylint problem. Perhaps we could discuss there?

Clippy is synced every other week. Next sync is on 2023-09-21. Since this is the first issue ever opened for dylint conflicts with the rust toolchain used to compile Clippy, I'd rather not do a out-of-cycle sync for this.

Why can't you use an older nightly toolchain for you dylint?

[EFanZh]

@flip1995 There is a certain bugfix of the Rust compiler required by our project, and it is only included in nightly-2023-09-10 or later version.

[flip1995]

What's the bugfix? Do you have a PR?

[EFanZh]

This one: rust-lang/rust#115638. Since the next sync is only 7 days later, I think I’ll just wait till then. Thank you all for your help!

FYI: I finally got to the toolchain update: #11563

Sorry for the delay!
