Rust Development in VS Code
VS Code with rust-analyzer provides one of the best Rust development experiences available. This lesson sets up a full Rust workflow with cargo, testing, and debugging.
1Setting Up the Rust Extension
Install rust-analyzer from the marketplace. It provides blazing-fast IntelliSense, macro expansion, type inference hints, and comprehensive refactoring for Rust. Also install CodeLLDB for debugging.

2Cargo Integration
VS Code auto-detects Cargo.toml and shows run/debug buttons in the gutter for tests and fn main(). The Terminal auto-completes cargo subcommands. The Even Better TOML extension adds rich TOML editing for Cargo.toml.

4Debugging Rust with CodeLLDB
{ "type": "lldb", "request": "launch", "name": "Debug", "cargo": { "args": ["build"] }, "args": [] }
5Clippy & Rustfmt
Enable Clippy as the check command in settings: "rust-analyzer.check.command": "clippy". Rustfmt formats on save automatically. Both integrate with the Problems panel so every lint suggestion is a clickable, fix-able item.
