What it does

Checks for unnecessary ok() in while let.

Why is this bad?

Calling ok() in while let is unnecessary, instead match on Ok(pat)

Example

while let Some(value) = iter.next().ok() {
    vec.push(value)
}

if let Some(value) = iter.next().ok() {
    vec.push(value)
}

Use instead:

while let Ok(value) = iter.next() {
    vec.push(value)
}

if let Ok(value) = iter.next() {
       vec.push(value)
}
