Struct TreeNode 

pub struct TreeNode {

    pub title: String,
    pub structure: String,
    pub content: String,
    pub summary: String,
    pub depth: usize,
    pub start_index: usize,
    pub end_index: usize,
    pub start_page: Option<usize>,
    pub end_page: Option<usize>,
    pub node_id: Option<String>,
    pub physical_index: Option<String>,
    pub token_count: Option<usize>,
    pub references: Vec<NodeReference>,
}

A node in the Vectorless document tree.

Each branch represents a section and each leaf contains the actual text. When a question is asked, an LLM navigates this tree level by level to find the right answer.

Fields

title: String

Title of this section.

structure: String

Hierarchical structure index (e.g., “1”, “1.1”, “1.2.3”).

This provides a human-readable path to the node and is useful for:

• LLM navigation (easier to understand “go to section 2.1.3”)
• Table of contents display
• Cross-referencing

content: String

Raw text content (populated at leaves).

summary: String

Generated by LLM summary.

depth: usize

Depth in tree (0 = root, 1 = section, 2 = subsection, etc.).

start_index: usize

Starting line number (1-based).

end_index: usize

Ending line number (1-based).

start_page: Option<usize>

Starting page number (1-based, if applicable).

end_page: Option<usize>

Ending page number (1-based, if applicable).

node_id: Option<String>

Unique node identifier (e.g., “0001”, “0002”).

physical_index: Option<String>

Physical index marker for line tracking.

token_count: Option<usize>

Token count estimate.

references: Vec<NodeReference>

References found in this node’s content.

These are in-document references like “see Appendix G” or “refer to Table 5.3” that can be followed during retrieval.

Trait Implementations
