Stuart Cook 4fc94eb558 Rollup merge of #151783 - mu001999-contrib:impl/final-method, r=fee1-dead
Implement RFC 3678: Final trait methods

Tracking: https://github.com/rust-lang/rust/issues/131179

This PR is based on rust-lang/rust#130802, with some minor changes and conflict resolution.

Futhermore, this PR excludes final methods from the vtable of a dyn Trait.

And some excerpt from the original PR description:
> Implements the surface part of https://github.com/rust-lang/rfcs/pull/3678.
>
> I'm using the word "method" in the title, but in the diagnostics and the feature gate I used "associated function", since that's more accurate.

rust-analyzer is a language server that provides IDE functionality for writing Rust programs. You can use it with any editor that supports the Language Server Protocol (VS Code, Vim, Emacs, Zed, etc).

rust-analyzer features include go-to-definition, find-all-references, refactorings and code completion. rust-analyzer also supports integrated formatting (with rustfmt) and integrated diagnostics (with rustc and clippy).

Internally, rust-analyzer is structured as a set of libraries for analyzing Rust code. See Architecture in the manual.
