HtmlDocument

Struct HtmlDocument 

Source
pub struct HtmlDocument {
    text: String,
    base: HtmlBase,
}
Expand description

HTML document backed by the hand-rolled XmlParser.

Node offsets are exact byte positions in the source string, making this suitable for EPUB spine chapters and standalone HTML files where reading positions are persisted to disk as absolute byte offsets.

Fields§

§text: String

The raw source text, retained so that Document::save can write it back to disk unchanged.

§base: HtmlBase

Shared rendering state.

Implementations§

Source§

impl HtmlDocument

Source

pub fn new<P: AsRef<Path>>(path: P) -> Result<HtmlDocument, Error>

Opens the file at path, parses it with XmlParser, and returns a ready-to-render document.

Source

pub fn new_from_memory(text: &str) -> HtmlDocument

Parses an in-memory HTML string and returns a ready-to-render document.

The document has no parent directory, so relative resource references (images, linked stylesheets) will not be resolved.

Source

pub fn update(&mut self, text: &str)

Replaces the document content with a freshly parsed version of text and clears the page cache.

Source

pub fn set_margin(&mut self, margin: &Edge)

Overrides the page margin. Clears the page cache.

Source

pub fn set_font_size(&mut self, font_size: f32)

Overrides the base font size in points. Clears the page cache.

Source

pub fn set_viewer_stylesheet<P: AsRef<Path>>(&mut self, path: P)

Overrides the viewer stylesheet path. Clears the page cache.

Source

pub fn set_user_stylesheet<P: AsRef<Path>>(&mut self, path: P)

Overrides the user stylesheet path. Clears the page cache.

Source

pub fn categories(&self) -> Option<String>

Always returns None; category metadata is not embedded in HTML files.

Source

pub fn description(&self) -> Option<String>

Returns the content of <meta name="description"> if present.

Source

pub fn language(&self) -> Option<String>

Returns the xml:lang attribute of the root <html> element if present.

Source

pub fn year(&self) -> Option<String>

Returns the first four characters of the content of <meta name="date"> (i.e. the year) if present.
