Implementations

impl TocElement

pub fn new<S1: Into<String>, S2: Into<String>>(url: S1, title: S2) -> TocElement

Creates a new element of the toc

By default, the element’s level is 1 and it has no children.

pub fn raw_title<S: Into<String>>(self, title: S) -> TocElement

Adds an alternate version of the title without HTML tags.

Useful only if you disable escaping of HTML fields.

pub fn level(self, level: i32) -> Self

Sets the level of a TocElement

pub fn child(self, child: TocElement) -> Self

Add a child to this element.

This adjust the level of the child to be the level of its parents, plus 1; this means that there is no point in manually setting the level to elements added with this method.

Example

use epub_builder::TocElement;
let elem = TocElement::new("foo.xhtml", "Foo")
    .child(TocElement::new("bar.xhtml", "Bar")
         .level(42));

// `Bar`'s level wiss still be `2`.

pub fn add(&mut self, element: TocElement)

Add element to self or to children, according to its level

This will adds element directly to self if its level is equal or less to the last children element; else it will insert it to the last child.

See the add method of `Toc.
