Found while with constant condition RS-W1077
Anti-pattern
Minor
A while loop with a constant condition will either never run or enter an infinite loop. If intentional, consider using a loop statement instead.
For example, if the while loop has a condition that is always true,
the lint will trigger a warning indicating that the loop is an infinite loop.
On the other hand, if the while loop has a condition that is always false, the lint will trigger a warning indicating that the loop will never run.
Bad practice
fn main() {
let x = 0;
while x < 5 {
println!("x = {}", x);
x += 1;
}
let y = 0;
while true {
// ^^^^ the lint will trigger a warning here
// indicating that this condition is not valid
// and the while loop will be an infinite loop
println!("y = {}", y);
y += 1;
}
}
Recommended
fn main() {
let x = 0;
while x < 5 {
println!("x = {}", x);
x += 1;
}
let y = 0;
loop {
// either make it explicit with loop
// or refactor it if it's a bug
println!("y = {}", y);
y += 1;
}
}
