== Why is this an issue?
|
||
|
|
|
||
|
|
Having an immutable condition in a while loop can result in an infinite loop as the condition will never change, causing the loop to run indefinitely.

==== Noncompliant code example
|
||
|
|
|
||
|
|
[source,rust,diff-id=1,diff-type=noncompliant]
|
||
|
|
----
|
||
|
|
let i = 0;
|
||
|
|
while i > 10 {
|
||
|
|
println!("let me loop forever!"); // Noncompliant: 'i' does not change within the loop body
|
||
|
|
}
|
||
|
|
----
|
||
|
|
|
||
|
|
==== Compliant solution
|
||
|
|
|
||
|
|
[source,rust,diff-id=1,diff-type=compliant]
|
||
|
|
----
|
||
|
|
let mut i = 0;
|
||
|
|
while i <= 10 {
|
||
|
|
println!("looping: {}", i); // Compliant: 'i' gets incremented within the loop body
|
||
|
|
i += 1;
|
||
|
|
}
