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 language = doc.mdata("language");
assert_eq!(language.unwrap().value, "es");

§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().path, Path::new("OEBPS/Text/titlepage.xhtml"));
assert_eq!(tpage.unwrap().mime, "application/xhtml+xml");

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);
use epub::doc::EpubDoc;
let doc = EpubDoc::new("test.epub");
let mut doc = doc.unwrap();
assert_eq!(0, doc.get_current_chapter());
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_chapter(2);
assert_eq!("001.xhtml", doc.get_current_id().unwrap());
assert_eq!(2, doc.get_current_chapter());
assert!(!doc.set_current_chapter(50));

// doc.get_current() will return a Vec<u8> with the current chapter content
// doc.get_current_str() will return a String with the current chapter content

§Getting the cover

ⓘ
use std::fs;
use std::io::Write;
use epub::doc::EpubDoc;

let doc = EpubDoc::new("test.epub");
assert!(doc.is_ok());
let mut doc = doc.unwrap();

let cover_data = doc.get_cover().unwrap();

let f = fs::File::create("/tmp/cover.png");
assert!(f.is_ok());
let mut f = f.unwrap();
let resp = f.write_all(&cover_data);
