Struct TocEntry 

pub struct TocEntry {
    pub label: String,
    pub href: String,
    pub children: Vec<TocEntry>,
}

An entry in the EPUB table of contents.

EPUB navigation uses NCX (Navigation Control for XML) files which define a hierarchical structure of navigation points. Each entry can have child entries, creating a tree structure.

Example

use epub_parser::TocEntry;

let mut toc_entry = TocEntry::new("Chapter 1".to_string(), "chapter1.xhtml".to_string());
toc_entry.children.push(TocEntry::new(
    "Section 1.1".to_string(),
    "chapter1.xhtml#section1".to_string()
));

println!("Entry: {} -> {}", toc_entry.label, toc_entry.href);
for child in &toc_entry.children {
    println!("  Child: {} -> {}", child.label, child.href);
}

Fields

label: String

The display label or title for this navigation point.

This is the text that would be shown in a table of contents.

href: String

The target URL for this navigation point.

This is a relative path within the EPUB, often with an anchor (e.g., “chapter1.xhtml” or “chapter1.xhtml#section1”).

children: Vec<TocEntry>

Child navigation entries.

The NCX format supports hierarchical navigation, so each entry can have nested sub-entries.

Implementations

impl TocEntry

pub fn new(label: String, href: String) -> Self

Creates a new TOC entry with the given label and href.

The children vector is initialized as empty.

Arguments

• label - The display text for this entry.
• href - The target URL/path for this entry.

Returns

A new TocEntry instance with empty children.

Example

use epub_parser::TocEntry;

let entry = TocEntry::new("Introduction".to_string(), "intro.xhtml".to_string());
assert_eq!(entry.label, "Introduction");
assert_eq!(entry.href, "intro.xhtml");
assert!(entry.children.is_empty());
