Non-modifying utility functions for the cell hierarchy.. Import the this trait to use the utility functions all types that implement the HierarchyBase trait.

Provided Methods§

source

fn is_top_level_cell(&self, cell: &Self::CellId) -> bool

Check if the cell is a top level cell. This is done by checking that no other cells have an instance of this cell.

source

fn is_leaf_cell(&self, cell: &Self::CellId) -> bool

Check if the cell is a leaf cell. This is done by checking that this cell contains no other cell instances.

source

fn each_top_level_cell(&self) -> Box<dyn Iterator<Item = Self::CellId> + '_>

Iterate over all top level cells.

source

fn each_leaf_cell(&self) -> Box<dyn Iterator<Item = Self::CellId> + '_>

Iterate over all leaf cells, i.e. cells which contain no other cells.

source

fn each_cell_bottom_to_top(&self) -> Box<dyn Iterator<Item = Self::CellId> + '_>

Iterate over topologically sorted cells (from leaf-cells to top-cells).
