I decided to take a stab at #89 just to see how feasible it is. In order to facilitate this, I have temporarily changed the API of
print_all
to takeInput
with a new genericBox <dyn Read>
variant as a fallback.So far, this implementation is only able to use sparseness when there is non-sparse content at the end of the file, and the rest of the file, including the start, is sparse. Otherwise, it will cause strange errors.
It also only works for Linux, because this was the simplest OS to implement sparse support for.

Tasks:
BufReader
