🆕 What's New in v0.11.0

Legacy Non-UTF-8 Charset Decoding (encoding_rs) — Decodes legacy charsets (Windows-1252, Shift-JIS, GBK, ISO-8859-1) into clean UTF-8 strings for 100% parse success across legacy MOBI, FB2, and TXT files.
Automatic Language Detection (whatlang) — Fast statistical language identification on text contents (book.detect_language()) when OPF metadata dc:language is missing.
Zstd Compressed State Caching (zstd) — Sub-millisecond instant serialization and restoration of parsed book states (book.export_zstd_cache(), Book::from_zstd_cache()) for high-throughput servers and WASM runtimes.

🚀 Quick Start Example

use ebook_rs::{Book, ReflowPaginator, Cfi};

fn main() -> Result<(), String> {
    // Auto-detects and opens EPUB, MOBI, AZW3, FB2, KEPUB, LIT, CBZ, PDF, ODT, TXT, MD
    let mut book = Book::from_file("book.epub")?;

    println!("Title: {}", book.metadata().title);
    println!("Sections: {}", book.spine().len());

    // Export any format to standard binary EPUB3 ZIP bytes
    let epub3_bytes = book.export_epub3_bytes()?;

    // Search with surrounding context snippets and <mark> highlights
    let search_results = book.search("quantum");
    for res in search_results {
        println!("Snippet: {}", res.snippet);
    }

    Ok(())
}
