Cargo tool ecosystem integration

Quick Setup

# Run the setup command (after installing the plugin)
/setup

Or manually:

# Install rust-analyzer
rustup component add rust-analyzer

# Install nightly toolchain (required for some tools)
rustup toolchain install nightly

# Install all cargo tools
cargo install cargo-audit cargo-deny cargo-outdated cargo-machete \
              cargo-semver-checks cargo-geiger cargo-expand cargo-bloat \
              cargo-mutants && \
cargo +nightly install cargo-udeps

Features

LSP Integration

The plugin configures rust-analyzer for Claude Code via .lsp.json:

        "command": "rust-analyzer",
        "args": [],
        "extensionToLanguage": { ".rs": "rust" },
        "transport": "stdio"
    }
}

Capabilities:

Go to definition / references
Hover documentation
Code actions and quick fixes
Workspace symbol search
Real-time diagnostics
