+== Why is this an issue?
+Calling `.step_by(0)` on an iterator will cause the program to panic. This is likely an oversight and should be corrected to ensure program stability. If the intent is to cause a panic, it is clearer to use `panic!()` directly.

+----
+for x in (0..100).step_by(0) { // Noncompliant: This will cause a panic.
+// ...
+}

+
+==== Compliant solution
+
+[source,rust,diff-id=1,diff-type=compliant]
+----
+for x in (0..100).step_by(1) { // Compliant: Step by a valid positive integer.
