livedisk

Cross-platform enumeration of the live system's physical disks and partitions — diskutil list / lsblk / diskpart, but as a library with one unified model across macOS, Linux, and Windows.

for disk in livedisk::enumerate()? {
    println!("{} — {}", disk.name, livedisk::human_size(disk.size_bytes));
    for part in &disk.partitions {
        println!("  {} {}", part.name, livedisk::human_size(part.size_bytes));
    }
}
# Ok::<(), livedisk::Error>(())

Discovery is the only OS-specific part. Each backend (sysfs on Linux, the IOKit IOMedia registry on macOS, DeviceIoControl on Windows) fills the same [PhysicalDisk]/[Partition] structs; everything downstream — the [render_overview] bar chart, the per-disk [render_disk_bar], the [render_listing] view, and the JSON form — is platform-agnostic.

[open_device] opens a chosen device node as a sized Read + Seek so a partition/filesystem analyzer can run on the live disk exactly as it would on an image file.

Listing layout/metadata works unprivileged on all three platforms (it reads the kernel's device registry, not raw sectors); only reading a device needs root/Administrator. Backends therefore never silently return an empty list on a permission problem — they surface [Error].
