support for range formatting

[ip-ragmatic]

Hello anyone reading this, I was wondering if there is any plans for further development of support range formatting. In the Configuration section of the manual there's a rust-analyzer.rustfmt.rangeFormatting.enable config that enables rustfmt's unstable range formatting for textDocument/rangeFormatting on nightly build. I've enabled this configuration.

I'm not sure if it's relevant to this discussion, but I'm using Helix and am trying to format a selection (using = key bound to format_selections). When I'm running RA stable, I get the error No configured language server supports range formatting when trying to format selection, and when I'm using RA nightly (64a1405) the error doesn't pop up but the code I selected doesn't get formatted.

Also, I've enabled this in my helix/languages.toml file. But is there a separate place I need to enable this for RA itself? I installed the RA nightly binary, if that's of importance.

By the way, RA is awesome so thank you to all the people who are contributing to it!

I'm not sure about helix, but in VS Code I had to:

• run rustup +nightly component add rustfmt (you also need to install the toolchain, of course)
• enable rust-analyzer.rustfmt.rangeFormatting.enable
• restart
• set rust-analyzer.rustfmt.extraArgs to ["+nightly"]

Okay, I'll give that a shot. Thanks
