title: Creating UUIDs in Elixir
body: <p>What's a canonical way to generate UUIDs in Elixir? Should I necessarily use the library <a href="https://hex.pm/packages/uuid" rel="noreferrer">https://hex.pm/packages/uuid</a> or is there a built-in library? I better have less dependencies and do more work than vise versa, therefore if I can generate in Elixir with an external dependency, it'll better go with it.</p>
