  </code></pre>
  <p>My <code>cargo.toml</code> file look like this:</p>
  <pre><code>[package]
  name = &quot;FlexDB&quot;
  version = &quot;0.1.0&quot;
  edition = &quot;2018&quot;
  
  # See more keys and their definitions at https://doc.rust-lang.org/cargo/reference/manifest.html
  
  [dependencies]
  anyhow = &quot;1&quot;

  <p>I don't know what to do, I did:</p>
  <ol>
  <li><code>rustup update</code></li>
