Module FeatureState 

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
