Thanks for catching these. It has been a long while since I last touched this piece of the code but the off-by-one fixes seem correct to me. I'm just not sure about removing the explicit self.end == 0
checks. Those still seem necessary to me.
if self.end == 0 { | ||
1..0 | ||
} else { | ||
0..self.end - 1 | ||
} | ||
0..self.end - 1 |

Wouldn't this panic when overflow checking is enabled (such as when building with debug)?
And even if the underflow does not panic it would return 0..usize::MAX
as the iterator for a range of x..0
. This is incorrect because the range should be empty. Similar reasoning applies to the other range implementations.

nom::multi::many
andnom::many::fold
consider empty ranges, as checked byNomRange::is_inverted
, to be invalid. Unfortunately, that method is incorrectly implemented forRangeTo
, meaning that..0
is not considered invalid when it should be.While I'm here, I also fixed up off-by-one errors in
RangeFrom::bounded_iter
andRangeFull::bounded_iter
.
