mobi-rs

A library written in rust to extract data from .mobi format ebooks It's purely for the sake of learning.

TODO:

• Implement lz77 decompression
• Write tests
• Proper file hierarchy
• Comments!
• Prepare for cargo

Example

Writing a program like this:

use mobi::Mobi;

fn main() {
    let m = Mobi::init(Path::new("/home/wojtek/Downloads/lotr.mobi"));
    println!(
        "{:#?} {:#?} {:#?} {:#?}",
        m.header, m.palmdoc, m.mobi, m.exth
    );
}

Would yield such result:
