Struct TreeNode 

pub struct TreeNode<'a> {
    pub concept_name: &'a str,
    pub labels: &'a [Label],
    pub depth: usize,
    pub fact_indices: Vec<usize>,
    pub children: Vec<TreeNode<'a>>,
}

A single node in the presentation hierarchy.

Fields

concept_name: &'a str

Concept name (e.g. bs.ass).

labels: &'a [Label]

All labels for this concept. The caller selects the desired language and role (e.g. terseLabel, label).

depth: usize

Depth in the tree; root nodes have depth 0.

fact_indices: Vec<usize>

Indices into the InstanceDocument::facts() slice for facts whose concept maps to this concept name.

Storing indices rather than references means the view’s lifetime is tied only to the taxonomy, leaving the instance free to be mutably borrowed while the view is alive.

children: Vec<TreeNode<'a>>

Child nodes, ordered by the presentation arc order attribute.

Trait Implementations
