Question about rust analyzer

[qvc0]

What should i do if i installed rust analyzer manually through a command on rust website, but helix doesn't launch it when i edit rust files, it recommends me to download rust-analyzer with arch repository?

rust-analyzer needs to be on PATH, and I don't think rustup adds it to PATH. You can either add it to PATH yourself or create a local languages.toml with

[language-server.rust-analyzer]
command = "rustup"
args = ["rust-analyzer"]
