Emacs has now two LSP clients, the more minimalistic and lightweight Eglot and
the extensive though a bit bloated LSP-Mode. Eglot will soon be
shipped with Emacs29. Both have rust-analyzer enabled by default and require
no further setup then just being installed and enabled. `lsp-rust.el` is not
required anymore.
The base-installation for each of those modes is so easy now that I don't think
an enumerated list is necessary, both package can be installed via the standard
`M-x package-install` and the installation is a one-liner that I provide.
Configuration mostly comes into play for support the rust-analyzer extensions to
the LSP protocol, which are built into LSP mode and require an extension-package
for Eglot.
But for the configuration beyond the base configuration I link against official
documentation, quickstart guides and documentation for the lsp extensions, to
avoid showing outdated information here.
This commit is mostly a duplicate of a PR [1] that I made against the
rust-analyzer github project.

Spelling: Space before version number in Emacs 29 in manual
Co-authored-by: Laurențiu Nicola <lnicola@users.noreply.github.com>
`rustup` can now install `rust-analyzer` for the stable tool-chain. This commit removes the note that `rustup` can only install for the nightly branch and adjusts the command.
I also added a note on how to find the path to the `rust-analyzer` binary when installed using `rustup`, and suggestions on how to work around it not being placed in `~/.cargo/bin`.
I thought it would be ideal to point everyone to use `rustup run stable rust-analyzer` to start `rust-analyzer`. That would make it trivial to switch to nightly however I could not get this to work in `nvim` therefore I left it as a suggestion at the end.
Keep things consistent with the package.json , which uses `self` and
`crate` instead of `by_self` and `by_crate`. Both names are in fact
allowed as aliases, but we should be consistent so that people reading
the docs and using a schema do not see red squiggles.
Closes#6883
This functionality was changed as of #11445 and now can be customized using native VSCode settings instead of `rust-analyzer`-specific ones.
