hadris-optical

hadris-optical is the optical-media facade for Hadris. It provides non-destructive ISO 9660/UDF detection, policy-based opening, and hybrid ISO+UDF image creation while retaining lossless access to the concrete format handles.

Detection reports ISO 9660 and UDF independently because bridge images can validly contain both filesystems.

[dependencies]
hadris-optical = "2.1.0"

use hadris_optical::{OpenPolicy, sync::OpenOpticalImage};
use std::fs::File;

let mut image = File::open("disc.iso")?;
let opened = OpenOpticalImage::open(&mut image, OpenPolicy::PreferUdf)?;

if let Some(udf) = opened.as_udf() {
    println!("UDF volume: {}", udf.info().volume_id);
}
# Ok::<(), Box<dyn std::error::Error>>(())

OpenPolicy can require one format or express a preference for bridge images. The returned enum preserves the underlying hadris-iso or hadris-udf handle.

Features

The hybrid cd writer is currently synchronous. For format-specific controls, use the re-exported iso, udf, and cd modules directly.
