== 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.


=== Code examples

==== Noncompliant code example
[source,rust,diff-id=1,diff-type=noncompliant]
----
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.
// ...
}
----
