Module DocumentState 

DocumentState Module (ApplicationState)

RESPONSIBILITIES

Manages open documents state including document metadata, content, and version tracking.

ARCHITECTURAL ROLE

DocumentState is part of the FeatureState module, representing open documents state organized by document URI.

KEY COMPONENTS

• DocumentState: Main struct containing open documents map
• Default: Initialization implementation
• Helper methods: Document 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 document validation invariants
• Implement document lifecycle events
• Add document metrics collection
