This is a rust-analyzer issue. You probably have an outdated rust-analyzer installation relative to your rust installation.

[DoctorRyner]

Oh, sorry, it's true. For some reason rustup doesn't install appropriate version of rust-analyser so I had to install the binary from their repo

[calbaker]

@DoctorRyner , I'm on an M1 ARM Mac and struggling to install the binary. Is there any chance you know how to do this on Mac?

[DoctorRyner]

@calbaker you can find M1 binary here https://github.com/rust-lang/rust-analyzer/releases

I use M1 Max myself

[calbaker]

@DoctorRyner , so you download rust-analyzer-darwin-arm64.vsix? I assume after that:

1. find the executable in the extracted folder
2. move the executable somewhere on the PATH and set the right permissions (which permissions are right for this?)
3. ...
4. PROFIT!!!

Could you steer me right wherever I'm wrong here?

[kirawi]

Is the file named rust-analyzer?

[DoctorRyner]

There is .gz file, I don't even know what vsix is. You just rename it to rust-analyzer and put it in the path

[kirawi]

Ah, I looked it up. vsix is for Visual Studio. Yeah you want the zip instead.
