Error when launching Rust debug

[fnuttens]

Hi! Since I'm not sure whether I stumbled on a bug or I'm simply doing things wrong, I'd rather open this discussion than an issue 😅

I'm trying to debug a dummy console app on Windows, made with cargo new.

Needless to say that the program compiles et executes with no hiccup.
However, I get the following error when I run the command :debug-start binary target\debug\playground.exe:

error: 'Content-Length' is not a valid command.
*a few moments later*
Failed to initialize debug adapter: request timed out

After that the interface gets all buggy, I have to restart helix.

The logs look like this:

2023-01-23T22:57:58.157 helix_dap::transport [INFO] -> DAP {"type":"request","seq":0,"command":"initialize","arguments":{"adapterID":"lldb-vscode","clientID":"hx","clientName":"helix","columnsStartAt1":true,"linesStartAt1":true,"locale":"en-us","pathFormat":"path","supportsInvalidatedEvent":false,"supportsMemoryReferences":false,"supportsProgressReporting":false,"supportsRunInTerminalRequest":true,"supportsVariablePaging":false,"supportsVariableType":true}}

The time out might indicate an issue with the rust debugger itself, but hx --health rust is all green 🤷🏻‍♂️

Any idea what I might be doing wrong?

Instead of using :debug-start, have you tried:

• <space>, then g to go to debug
• b to toggle breakpoint
• l to launch debug target
• enter the binary path

Don't forget the check the latest wiki.

Thanks for helping!

Yes I've tried this and I had the same error… Maybe I shouldn't be using the MSVC toolchain?
I will also try to use codelldb instead of lldb-vscode.

Looks like you are using lldb-vscode from codelldb.

Have you tried to install llvm by using chocolatey?

Hey @quantonganh, sorry for not replying sooner, I just gave this another try and I finally got the hang of it! In the end I managed to use codelldb with the configuration from the wiki. Thanks!
