Not a defect when
The code is a test that deliberately builds a reversed range to check how an API handles empty input.
What it reads
Clippy, with the compiler behind it. The only pass that compiles.
Tier
Serious: worth interrupting other work for.
The tier bounds how severe a rule may be; its category bounds the tier.Diff scope
The changed line itself.

Turn it off, or make it blocking, without touching the code it flags:
rust-doctor --rule clippy::reversed_empty_ranges=off .
rust-doctor --rule clippy::reversed_empty_ranges=error .
