Does this only work with files or can any source be used as long as it is a Stream? Basically, I'd love to have something like this for arbitrary data, not just files.

Also, looks like the README has a broken link: https://librsync.github.io/rdiff.html

Yep, Streams or Pipes for IO. No seeking, forward-only reads - using this with network in/out was my goal.

Thanks for pointing out the broken link. Looks like it's here now: https://librsync.github.io/page_rdiff.html
