This can be used to avoid awkward
start..(end + 1)
constructions, which will trigger theclippy::range_plus_one
lint.I added a single impl for
InclusiveRange
rather than a blanketimpl<T: RangeBounds> From<T> for SourceSpan
for two reasons. The first is that the blanket impl would be a breaking change (because dependent crates may currently define a typeT: RangeBounds
and also haveimpl From<T> for SourceSpan
). The second is that this would allow one-sided ranges (..x
,x..
). In order to support bounded-below ranges, we would need to changeSourceSpan
so thatlength
may depend on the the specificSourceCode
instance. That seems like an unlikely use case.
