# Rust Analyzer LSP

Type checking, linting, and build verification for Rust projects. Runs
cargo commands after edits to catch errors before they compound.

## Workflow

1. After editing a .rs file, run `cargo check` on the project
2. If warnings exist, run `cargo clippy` for deeper analysis
3. Fix issues and re-check until clean
4. Run relevant tests with `cargo test`

## Commands

```bash
# Quick type check (fastest feedback)
cargo check

# Linting with Clippy
cargo clippy -- -W clippy::all

# Run tests
cargo test

# Build in release mode
cargo build --release
```

## Example usage

- "Check if my Rust code compiles"
- "Run clippy and fix all warnings"
- "What type errors do I have?"

## Requirements

- Rust toolchain (rustup)
- cargo and clippy installed
