  1. Build Navius - Build the project
  2. Run Tests - Run all tests
  3. Format Code - Format using rustfmt
  4. Check with Clippy - Run the Rust linter

To run a task:

  1. Press Ctrl+Shift+P (Cmd+Shift+P on macOS)
  2. Type "Run Task"
  3. Select the desired task

Essential Plugins

The following plugins enhance the development experience:

  1. Rust - Core Rust language support
  2. Database Navigator - Database support for PostgreSQL
  3. EnvFile - Environment file support
  4. GitToolBox - Enhanced Git integration

Run Configurations

Create the following run configurations:

  1. Go to Run → Edit Configurations
  2. Click the + button and select "Cargo"
  3. Set the name to "Run Navius Server"
  4. Set Command to "run"
  5. Set Working directory to the project root
  6. Add the following environment variables:
    • RUST_LOG=debug
    • CONFIG_DIR=./config
    • RUN_ENV=development

Test Configuration

  1. Go to Run → Edit Configurations
  2. Click the + button and select "Cargo"
  3. Set the name to "Run Navius Tests"
  4. Set Command to "test"
  5. Set Working directory to the project root

Debugging

JetBrains IDEs provide robust debugging support:

  1. Set breakpoints by clicking in the gutter
  2. Start debugging by clicking the debug icon next to your run configuration
  3. Use the Debug tool window to inspect variables, evaluate expressions, and control execution flow

Other IDEs

Vim/Neovim

For Vim/Neovim users:

  1. Install rust-analyzer language server:

    rustup component add rust-analyzer

  2. Configure a language server client like coc.nvim or built-in LSP for Neovim

  3. Add the following to your Vim/Neovim configuration:

    " For coc.nvim
let g:coc_global_extensions = ['coc-rust-analyzer']

    Or for Neovim's built-in LSP:

    require('lspconfig').rust_analyzer.setup{
  settings = {
    ["rust-analyzer"] = {
      assist = {
        importGranularity = "module",
        importPrefix = "self",
      },
      cargo = {
        loadOutDirsFromCheck = true
      },
      procMacro = {
        enable = true
      },
    }
  }
}

  "files.watcherExclude": {
    "**/target/**": true
  }
}

  • Night Owl - Excellent for night coding sessions

JetBrains IDEs

  • Darcula - Default dark theme with good Rust support
  • Material Theme UI - Modern look with good color coding
  • One Dark - Consistent coloring across code elements

Troubleshooting

Common Issues

Rust Analyzer Problems

  • Issue: Rust Analyzer stops working or shows incorrect errors
  • Solution:
    1. Restart the Rust Analyzer server
    2. Check that your Cargo.toml is valid
    3. Run cargo clean && cargo check to rebuild project metadata

Debugging Fails

  • Issue: Cannot hit breakpoints when debugging
  • Solution:
    1. Ensure LLDB or GDB is properly installed
    2. Check that you're running a debug build (cargo build)
    3. Verify launch configurations match your project structure

Performance Issues

  • Issue: IDE becomes slow when working with Navius
  • Solution:
    1. Exclude the target directory from indexing
    2. Increase available memory for the IDE
    3. Disable unused plugins/extensions
