Feature-specific state management.
§FeatureState Module (ApplicationState)
§RESPONSIBILITIES
Manages feature-specific state including diagnostics, documents, terminals, webviews, tree views, output channels, and markers.
§ARCHITECTURAL ROLE
FeatureState is part of the state organization layer, representing all feature-specific state in the application.
§KEY COMPONENTS
- Diagnostics: Diagnostic errors state
- Documents: Open documents state
- Terminals: Terminal instances state
- Webviews: Webview panels state
- TreeViews: Tree view providers state
- OutputChannels: Output channel state
- Markers: Marker state
- State: Main struct combining all feature state
§ERROR HANDLING
Uses Arc<Mutex<...>> for thread-safe access with proper error handling.
§LOGGING
State changes are logged at appropriate levels.
§PERFORMANCE CONSIDERATIONS
- Lock mutexes briefly
- Avoid nested locks
- Use Arc for shared ownership
§TODO
- Add feature state validation
- Implement feature lifecycle events
- Add feature metrics
