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
for x in (0..100).step_by(0) { // Noncompliant: This will cause a panic.
// ...
}
Compliant solution
for x in (0..100).step_by(1) { // Compliant: Step by a valid positive integer.
// ...
}
