Read files from a FAT image

[dependencies]
hadris-fat = "2.0.0"

use hadris_fat::{FatVolume, FatVolumeReadExt};
use std::fs::File;

fn main() -> hadris_fat::Result<()> {
    let image = File::open("disk.img")?;
    let volume = FatVolume::open(image)?;

    let root = volume.root_dir();
    let mut entries = root.entries();
    while let Some(Ok(entry)) = entries.next_entry() {
        println!("{} ({} bytes)", entry.name(), entry.len());
    }

    Ok(())
}

Use OpenOptions and the write extension traits when the same image must be modified. For a partitioned disk, create a bounded partition view with hadris-block before opening the FAT volume.
