EPUB library lib to read and navigate through an epub file contents
§Examples
§Opening
use epub::doc::EpubDoc;
let doc = EpubDoc::new("test.epub");
assert!(doc.is_ok());
let doc = doc.unwrap();
§Getting doc metadata
Metadata is a HashMap storing all metadata defined in the epub
let title = doc.mdata("title");
assert_eq!(title.unwrap(), "Todo es mío");§Accessing resources
In the resources var is stored each resource defined
in the epub indexed by the id and with the full internal
path and mimetype. It’s a HashMap<a: String, (b: String, c: String)>
where a is the resource id, b is the resource full path and
c is the resource mimetype
assert_eq!(23, doc.resources.len());
let tpage = doc.resources.get("titlepage.xhtml");
assert_eq!(tpage.unwrap().0, Path::new("OEBPS/Text/titlepage.xhtml"));
assert_eq!(tpage.unwrap().1, "application/xhtml+xml");§Navigating using the spine
Spine is a Vec<String> storing the epub spine as resources ids
assert_eq!(17, doc.spine.len());
assert_eq!("titlepage.xhtml", doc.spine[0].idref);§Navigation using the doc internal state
use epub::doc::EpubDoc;
let doc = EpubDoc::new("test.epub");
let mut doc = doc.unwrap();
assert_eq!(0, doc.get_current_page());
assert_eq!("application/xhtml+xml", doc.get_current_mime().unwrap());
doc.go_next();
assert_eq!("000.xhtml", doc.get_current_id().unwrap());
doc.go_next();
assert_eq!("001.xhtml", doc.get_current_id().unwrap());
doc.go_prev();
assert_eq!("000.xhtml", doc.get_current_id().unwrap());
doc.set_current_page(2);
assert_eq!("001.xhtml", doc.get_current_id().unwrap());
assert_eq!(2, doc.get_current_page());
assert!(!doc.set_current_page(50));
// doc.get_current() will return a Vec<u8> with the current page content
// doc.get_current_str() will return a String with the current page content§Getting the cover
