Struct TextSegment 

pub struct TextSegment {
    pub start: usize,
    pub end: usize,
    pub tag: String,
    pub id: Option<String>,
    pub src: Option<String>,
    pub caption: Option<String>,
    pub indent: f32,
    pub styles: Vec<StyleRun>,
}

A run of chapter text belonging to one block element, with its char range. For <img>/<figure> segments the text range is empty (zero-width marker at the image’s flow position) and src/caption carry the image data.

Fields

start: usize

Inclusive start byte/char offset into the chapter text.

end: usize

Exclusive end offset.

tag: String

Element tag (e.g. p, h1, li, img, figure).

id: Option<String>

The element’s id attribute if any (useful for anchoring).

src: Option<String>

src for img/figure (None for text blocks).

caption: Option<String>

figcaption text for a figure (None for non-figures).

indent: f32

Left indent of the block, in em, resolved from the book’s stylesheet (see crate::html_text::style) plus any leading spaces the markup kept. 0 for ordinary prose. Serde-defaulted so offset caches written before indents existed still deserialize.

styles: Vec<StyleRun>

Bold/italic spans within this segment, in chapter-text offsets.
