Hole-Punch

A (wip) dead simple, cross platform crate for finding the locations of holes in sparse files.

Currently only supports Unix, but Windows support is coming soon.

Usage

```rust use std::fs::File; use hole_punch::*;

let mut file = File::open("a big sparse file"); let segments = file.scanchunks().expect("Unable to scan chunks"); for segment in segement { if let SegementType::Data = segment.segmenttype { let start = segment.start; let end = segment.end;

    let length = end - start;
    do_something_with_data(&mut file, start, length);
}

} ```

TO-DOs

The following features are on my "to implement" list, in order of importance: 1. Windows support 2. Fallback mode (reading the entire file manually looking for chunks of 0s)
