Module DocumentProvider 

Source
Expand description

DocumentProvider: opens, closes, and tracks text document state.

§DocumentProvider (Environment)

Implements the DocumentProvider trait, managing the complete lifecycle of document operations including opening, saving, editing, and closing. It maintains document state, coordinates between the frontend (Sky), extension host (Cocoon), and filesystem, and handles both native file URIs and custom scheme URIs.

§Implementation Strategy

The trait implementation is split across multiple helper modules for maintainability:

  • OpenDocument: Document opening and content resolution (file:// and custom schemes)
  • SaveOperations: SaveDocument, SaveDocumentAs, SaveAllDocuments
  • ApplyChanges: ApplyDocumentChanges (incremental text edits)
  • Notifications: NotifyModelAdded, NotifyModelChanged, NotifyModelSaved, NotifyModelRemoved

The single impl DocumentProvider for MountainEnvironment block in this file delegates to those helper functions. This satisfies Rust’s orphan rules while keeping code organized and atomic.
