Format not work

[aleksanderd]

Hi!

I can not get vscode to format code, the error is:

[Trace - 9:32:34 PM] Received response 'textDocument/formatting - (15)' in 0ms. Request failed: Reformat failed to complete successfully (-32603).
[Error - 9:32:34 PM] Request textDocument/formatting failed.
  Message: Reformat failed to complete successfully
  Code: -32603 

rustftm via cmd formats same file ok.

what to check or configure?

thank you!

I just started learning Rust with VSCode and rls-vscode plugin and got the same error. To check what is the error message, click View > Open View and write Output (panel) then press Enter.

Unfortunately, this is an issue with RLS itself. That's high on the list so hopefully this will be soon resolved

Is the upstream issue rust-lang/rls#1397?

Any update about this issue?

I don't get an error, but I format does nothing on my end either

I got the same error.

Hi there

Issue a "cargo fmt" from within your project dir. This will give more information why formatting can not be used.
In my case my toolchain missed the cargo-fmt.exe. after that it worked from commandline and from within vscode

I have the same issue and "cargo fmt" works fine, no error when I run from the command line. It used to work until very recently within VSCode too, now I get the error reported above every time.

Same here, cargo fmt works but running Format Document gives me this error:

[Error - 4:45:32 PM] Request textDocument/formatting failed.
  Message: Reformat failed to complete successfully
  Code: -32603

I am using

rustc 1.37.0 (eae3437df 2019-08-13)
rustfmt 1.3.0-stable (d3345024 2019-06-09)
cargo 1.37.0 (9edd08916 2019-08-02)

I also noticed that the RLS [building] spinner in vscode's status bar never changes and there is no output except the above error when I save.

I have one machine running VS Code 1.37 that works properly, and another running 1.38.1 that does not work, so it looks like it was a regression from the earlier issue.

A simple warning for the fellow newbies who are just starting to learn Rust like me. It seems that you need a Cargo.toml file in your project so that rls-vscode formats your code.
