rust-analyzer for Vim/Neovim, works as an extension with coc.nvim.
:CocInstall coc-rust-analyzer
remove
rust-analyzerconfig fromcoc-settings.jsonif you've setNOTE: For Apple Silicon users, you shouldn't use Node.js v15, checkout #975 for more.
It's recommended to add $CARGO_HOME to workspace.ignoredFolders to stop rust-analyzer runs cargo check on sysroot crates:
"workspace.ignoredFolders": [
"$HOME",
"$HOME/.cargo/**",
