-Alan, using Rust for a little while now, has learned to follow compiler error messages and adds `async-trait` to the dependencies list. Alan follows the README of `async-trait` and gets the code to compile. Alan is somewhat dismayed that the compile times have increased considerably after adding this new dependency.
+Alan, who has been using Rust for a little while now, has learned to follow compiler error messages and adds `async-trait` to his `Cargo.toml`. Alan follows the README of `async-trait` and comes up with the following code:
+'''rust
+#[async_trait]
+trait HttpClient {
+    async fn perform(request: Request) -> Response;
+}
+'''
+Alan's code now compiles, but he also finds that his compile times have gone from under a second to around 6s, at least for a clean build.
 
 **TODO::** Maybe add representive pre and post trait compile times here.
