Developing Rust in Neovim

Overview

Here is a short set of instructions on how to get started with Rust in Neovim.

This guide assumes Neovim is already installed and that we are using vim-plug to manage its plugins.

Install

We need Rust.

curl https://sh.rustup.rs -sSf | sh

Install extras

We need rls for the LanguageClient plugin to check our code in real time.

rustup component add rls rust-analysis rust-src

The RLS provides a server that runs in the background, providing IDEs, editors, and other tools with information about Rust programs. It supports functionality such as ‘goto definition’, symbol search, reformatting, and code completion, and enables renaming and refactorings.

Install and configure IDE

Add the following to ~/.config/nvim/init.vim (or equivalent):

Plug 'autozimu/LanguageClient-neovim', {
    \ 'branch': 'next',
    \ 'do': 'bash install.sh',
    \ }

let g:LanguageClient_serverCommands = {
    \ 'rust': ['~/.cargo/bin/rustup', 'run', 'stable', 'rls'],
    \ }
