Module Main 

Main application entry point and orchestration.

Main Module (Binary)

RESPONSIBILITIES

Main application orchestration providing entry point, command handlers, lifecycle management, and tray integration for the Mountain desktop application.

This module serves as the primary entry point for the application and coordinates all initialization, execution, and shutdown operations.

ARCHITECTURAL ROLE

The Main module is the orchestration layer in Mountain’s architecture:

main.rs ──► Binary::Main (Entry::Fn)
                     │
                     ├─► Entry::Fn() (Main entry point)
                     ├─► IPCCommands (Tauri command handlers)
                     ├─► AppLifecycle (Setup and initialization)
                     └─► Tray (System tray icon management)

KEY COMPONENTS

• Entry (Entry::Fn): Main application entry point exported as Binary::Main::Fn()
• IPCCommands: All Tauri command handlers for frontend-backend communication
  • Workbench configuration commands
  • IPC messaging commands
  • Wind desktop configuration commands
  • Configuration management commands
  • Status reporting commands
  • Performance monitoring commands
  • Collaboration commands
  • Document sync commands
• AppLifecycle: Application lifecycle management and setup
• Tray: System tray icon switching based on theme

EXPORTS

• pub use Entry::Fn as Main: Main entry point
• All IPC command functions are exported from IPCCommands
• AppLifecycleSetup: Application setup function from AppLifecycle
• SwitchTrayIcon: Tray icon switching command from Tray

ERROR HANDLING

• Entry point panics on fatal errors (Tokio runtime, Tauri build)
• IPC commands return Result<serde_json::Value, String>
• Lifecycle setup returns Result<(), Box<dyn std::error::Error>>
• Non-critical failures are logged but don’t prevent operation

LOGGING

Comprehensive logging throughout with checkpoints at key stages. Logs use standardized prefixes: [Boot], [Lifecycle], [IPC], [UI].

PERFORMANCE CONSIDERATIONS

• Async initialization spawned after main setup
• Compile-time resource embedding for tray icons
• Minimal allocation overhead with efficient error handling

TODO

• Add comprehensive error recovery mechanism
• Implement startup progress indicator
• Add graceful degradation for service failures
• Implement performance metrics collection

Re-exports
