I guess this part is not true then because we avoid using hyper-util in examples.

### Using Examples in Your Own Project

When copying code from these examples into your own standalone project, note that
the examples in this repository import an internal support module (`#[path = "../benches/support/mod.rs"]`)
to avoid a cyclical workspace dependency on `hyper-util`.

In your own application, add `hyper-util` to your `Cargo.toml`:

```toml
hyper-util = { version = "0.1", features = ["tokio"] }
```

And import `TokioIo` and `TokioTimer` directly from `hyper_util::rt`:

```rust
use hyper_util::rt::{TokioIo, TokioTimer};
```
