Struct id_tree_layout::embedder::PlacedTreeItem

pub struct PlacedTreeItem {
    pub y_order: usize,
    pub x_center: usize,
    pub x_extent: usize,

The PlacedTreeItem is the embedding information for one single tree node. It is used only in a collection type Embedding. External API: keep stable.

Fields

y_order: usize

The nodes level, root has level 0. Can be used to calculate an y coordinate for the node

x_center: usize

The logical x coordinate of the node’s center

x_extent: usize

The x-extent of the nodes text representation in logical coordinate units

x_extent_children: usize

The maximum extent over the nodes text representation and the sum of all children’s x-extent

text: String

The text representation of the nodes data - created by the Visualize trait’s implementation

is_emphasized: bool

The emphasize property obtained from the Visualize trait

parent: Option<usize>

The parent’s ord, if there is one

ord: usize

A unique number reflecting the topological post-ordering of the nodes in the tree
