Module TreeViewState 

TreeViewState Module (ApplicationState)

RESPONSIBILITIES

Manages tree view providers state including tree view metadata, data, and presentation state.

ARCHITECTURAL ROLE

TreeViewState is part of the FeatureState module, representing tree view providers state organized by tree view ID.

KEY COMPONENTS

• TreeViewState: Main struct containing active tree views map
• Default: Initialization implementation
• Helper methods: Tree view manipulation utilities

ERROR HANDLING

• Thread-safe access via Arc<Mutex<...>>
• Proper lock error handling with MapLockError helpers

LOGGING

State changes are logged at appropriate levels (debug, info, warn, error).

PERFORMANCE CONSIDERATIONS

• Lock mutexes briefly and release immediately
• Avoid nested locks to prevent deadlocks
• Use Arc for shared ownership across threads

TODO

• Add tree view validation invariants
• Implement tree view lifecycle events
• Add tree view metrics collection
