   1 ### What it does
   2 Checks for unnecessary `ok()` in `while let`.
   3
   4 ### Why is this bad?
   5 Calling `ok()` in `while let` is unnecessary, instead match
   6 on `Ok(pat)`
   7
   8 ### Example
   9 ```
  10 while let Some(value) = iter.next().ok() {
  11     vec.push(value)
  12 }
  13
  14 if let Some(value) = iter.next().ok() {
  15     vec.push(value)
  16 }
  17 ```
  18 Use instead:
  19 ```
  20 while let Ok(value) = iter.next() {
  21     vec.push(value)
  22 }
  23
  24 if let Ok(value) = iter.next() {
  25        vec.push(value)
  26 }
  27 ```
