title: Is there some way to not show a warning for non snake case identifiers?
body: <p>I'm writing my first tests in Rust and I find this:</p>
  
  <blockquote>
    <p>warning: function <code>testCall</code> should have a snake case name such as
    <code>test_call</code>, #[warn(non_snake_case)] on by default</p>
  </blockquote>
  
  <p>after searching, I found <a href="https://aturon.github.io/style/naming.html" rel="noreferrer">this style guide</a>.</p>
  
  <p>I understand it is a convention, but is there some way to not show this warning?</p>
