Metadata

name: rust-analyzer-lsp
description: Rust language server (rust-analyzer) providing code intelligence and analysis for .rs files. Use when working with Rust code that needs autocomplete, go-to-definition, find references, error detection, or refactoring support.

rust-analyzer LSP

Rust language server integration providing comprehensive code intelligence through rust-analyzer.

Capabilities

Code intelligence: Autocomplete, go-to-definition, find references
Error detection: Real-time diagnostics for compilation errors
Refactoring: Rename symbols, extract function/variable
Analysis: Macro expansion, type hints, inlay hints
Supported extensions: .rs

Installation

Via rustup (recommended)

rustup component add rust-analyzer

Via Homebrew (macOS)

brew install rust-analyzer

Via package manager (Linux)

# Ubuntu/Debian
sudo apt install rust-analyzer

# Arch Linux
sudo pacman -S rust-analyzer

Manual download

Download pre-built binaries from the releases page.

Verify installation:

rust-analyzer --version

Usage

The language server runs automatically in LSP-compatible editors. For manual operations:

Format code

cargo fmt

Run linter

cargo clippy

Build and test

cargo build
cargo test

Check without building

cargo check

Configuration

Create .rust-analyzer.json in project root:

{
  "checkOnSave": {
    "command": "clippy"
  },
  "inlayHints": {
    "typeHints": true,
    "parameterHints": true
  }
}

Integration Pattern

When editing Rust code:

rust-analyzer provides real-time diagnostics
Run cargo fmt to format code
Use cargo clippy for linting
Run cargo test before committing

Common Cargo Commands

cargo new <name> - Create new project
cargo build - Compile project
cargo run - Build and run
cargo test - Run tests
cargo check - Fast compile check
cargo clippy - Run linter
cargo fmt - Format code
cargo doc --open - Generate and open docs
