== 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.

=== Code examples

==== 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;
}
