Enum DrawingSyncAction 

#[non_exhaustive]
pub enum DrawingSyncAction {
    SaveDrawing(usize),
    UpdateDrawing(usize),
    Delete(String),
    RestoreDrawings(Vec<StoredDrawing>),
}

A change to the stored drawings, queued in DrawingManager::pending_sync.

When enabled, every DrawingManager method that changes a stored drawing field queues an action per drawing it changes: creating, moving, styling, locking, hiding, layering, deleting, undo and redo. Restoring a stored drawing with DrawingManager::add_synced_drawing queues nothing. Repeated saves and updates coalesce until that drawing is deleted. The host drains the queue and saves or deletes each drawing it names, skipping saves of drawings already deleted, for example with drawing_to_stored. A host that writes to DrawingManager::drawings directly queues nothing. Automatic chart storage disables these notifications; use DrawingManager::set_sync_enabled to consume both paths.

Variants (Non-exhaustive)

Non-exhaustive enums could have additional variants added in future. Therefore, when matching against variants of non-exhaustive enums, an extra wildcard arm must be added to account for any future variants.

SaveDrawing(usize)

A new drawing was created and should be saved. Carries the drawing ID.

UpdateDrawing(usize)

An existing drawing was modified (moved, resized, styled). Carries the drawing ID.

Delete(String)

A drawing was deleted. Carries the stored drawing ID as a string.

RestoreDrawings(Vec<StoredDrawing>)

A batch of drawings should be restored from backend storage. The manager never queues it.
