   1 ### What it does
   2 This lint checks for equality comparisons with `ptr::null`
   3
   4 ### Why is this bad?
   5 It's easier and more readable to use the inherent
   6 `.is_null()`
   7 method instead
   8
   9 ### Example
  10 ```
  11 use std::ptr;
  12
  13 if x == ptr::null {
  14     // ..
  15 }
  16 ```
  17
  18 Use instead:
  19 ```
  20 if x.is_null() {
  21     // ..
  22 }
  23 ```
