+   |         ^^^^^
+   |         |
+   |         expected `i32`, found struct `RangeInclusive`
+   |         `RANGE` is interpreted as a constant, not a new binding
+   |
+   = note: expected type `i32`
+            found struct `RangeInclusive<i32>`
+   = note: constants only support matching by type, if you meant to match against a range of values, consider using a range pattern like `min ..= max` in the match block
