Expand description

Extension trait with extra methods implemented on types that implement Model

Provided Methods§

Convenience function that calls ModelTracker::track_row_data_changes before returning Model::row_data.

Calling row_data(row) does not register the row as a dependency when calling it while evaluating a property binding. This function calls track_row_data_changes(row) on the self.model_tracker() to enable tracking.

Returns a new Model where all elements are mapped by the function map_function. This is a shortcut for MapModel::new().

Returns a new Model where the elements are filtered by the function filter_function. This is a shortcut for FilterModel::new().

Returns a new Model where the elements are sorted ascending. This is a shortcut for SortModel::new_ascending().

Returns a new Model where the elements are sorted by the function sort_function. This is a shortcut for SortModel::new().
