Crate boko 

boko

A high-performance, format-agnostic ebook processing engine.

Architecture

Boko uses an Importer architecture for reading ebooks:

• Book is the runtime handle that wraps format-specific backends
• Importer trait defines the interface for format backends
• Lazy loading via ByteSource for efficient random access

Supported Formats

Format	Read	Write
EPUB	✓	✓
AZW3	✓	✓
MOBI	✓	-

Quick Start

use boko::Book;

let mut book = Book::open("input.epub")?;
println!("Title: {}", book.metadata().title);

// Iterate chapters (collect spine first to avoid borrow issues)
let spine: Vec<_> = book.spine().to_vec();
for entry in spine {
    let content = book.load_raw(entry.id)?;
    println!("Chapter: {} bytes", content.len());
}
