The memory-safe PDF library.

// The Result type makes error handling explicit — no segfaults possible.
// Buffer overflows and use-after-free bugs are eliminated by the Rust compiler.
fn process_pdf(path: &str) -> anyhow::Result<()> {
    // open() returns Result<Document, Error> — never a null pointer.
    let doc = PdfDocument::open(path)?;

    let page_count = doc.page_count();
    let title = doc.metadata().title().unwrap_or("(no title)");

    println!("Opened: {} ({} pages)", title, page_count);

    // doc is dropped here — memory is freed deterministically.
    // No garbage collector, no memory leak, no use-after-free.
    Ok(())
