==== Gentoo Linux
`rust-analyzer` is installed when the `rust-analyzer` USE flag is set for `dev-lang/rust` or `dev-lang/rust-bin`.
You also need to set the `rust-src` USE flag.
There are two ways to install `rust-analyzer` under Gentoo:
This is similar to using the `rustup` component, so it will install a version that lags behind the official releases on GitHub .
- when installing `dev-lang/rust` or `dev-lang/rust-bin`, enable the `rust-analyzer` and `rust-src` USE flags
- use the `rust-analyzer` component in `rustup` (see instructions above)
Note that in both cases, the version installed lags for a couple of months behind the official releases on GitHub.
To obtain a newer one, you can download a binary from GitHub Releases or building from source.
