Method delete_view

atomic-repository/src/repository/views.rs:393–455

Delete a view from the repository. This removes the view and all its associated metadata, but does not delete the changes themselves. Changes remain in the graph and may be referenced by other views. # Arguments `name` - The name of the view to delete # Errors Returns an error if: - The view does not exist - The view is the current view (cannot delete current view) - The database operation fa
