kennytm bd3674e4de Rollup merge of #48087 - scottmcm:range_is_empty, r=kennytm,alexcrichton ... Add Range[Inclusive]::is_empty During https://github.com/rust-lang/rfcs/pull/1980, it was discussed that figuring out whether a range is empty was subtle, and thus there should be a clear and obvious way to do it. It can't just be ExactSizeIterator::is_empty (also unstable) because not all ranges are ExactSize -- such as `Range<i64>` and `RangeInclusive<usize>`. Things to ponder: - Unless this is stabilized first, this makes stabilizing ExactSizeIterator::is_empty more icky, since this hides that. - This is only on `Range` and `RangeInclusive`, as those are the only ones where it's interesting. But one could argue that it should be on more for consistency, or on RangeArgument instead. - The bound on this is PartialOrd, since that works ok (see tests for float examples) and is consistent with `contains`. But ranges like `NAN..=NAN`_are_ kinda weird. - [x] ~~There's not a real issue number on this yet~~		2018-02-14 16:14:33 +08:00
