Vscode-rust: "no formatter for 'rust'-files installed" when formatting selection

[pepyakin]

When I try to execute command "Format selection" vscode says

Sorry, but there is no formatter for 'rust'-files installed.

Is it supported?

There are two formatting modes: Whole file and range formatting. Whole file formatting is stable and can always be used. Range formatting is unstable and only activated if you set "rust.unstable_features": true, in your config (Docs). It is currently behind a flag because range formatting can break your code.

FYI anyone finding this - "whole file" formatting shortcut is ctrl-shift-i

I have set "rust.unstable_features":true. However, I cannot execute command "Format selection" still. Has range formatting been removed?

It should pop up in the menu, yes. Are you using nightly?

Oh, thanks for your help! I am new to rust and using stable. After switching to nightly, I find this at the pop-up menu.

I also ran into the problem described in the original issue https://github.com/rust-lang-nursery/rls-vscode/issues/201#issue-277093998. In my case, uninstalling and re-installing the Rust (rls) extension in Visual Studio Code solved the problem.

I want to use only whole-file formatting. I don't have rust.unstable_features":true enabled. When I run Format Document using Option-Shift-F it says

There is no formatter for 'rust' files installed.

Is it possible to use Format Document without rust.unstable_features":true?

It works now after following these two steps of the Quick Start:

• Open a Rust project (File > Add Folder to Workspace...). Open the folder for the whole project (i.e., the folder containing 'Cargo.toml'), not the 'src' folder.
• You'll be prompted to install the RLS. Once installed, the RLS should start building your project.

I had simply opened a Rust source file, which was not sufficient to trigger installing RLS.

Just for my curiosity, is it possible to install RLS using rustup component add rls rust-analysis rust-src rather than Add Folder to Workspace?
