Implementing generic trait for a generic type concretely: snippet error?

I believe there is a mistake in the sample code in the https://brson.github.io/rust-anthology/1/rust-reuse-and-recycle.html.

`self` in the following snippet, is type `Generic` so must reference the `data` therein:

```rust
// Incorrect

// Implementing a generic trait for a generic type generically.
// Note that we have two generic types in play; T and U.
impl, U> Equal> for Generic {
fn equal(&self, other: &Generic) -> bool {
self.equal(&other.data) // <<< should be self.data.equal(&other.data)
}
}

// correct
impl, U> Equal> for Generic {
fn equal(&self, other: &Generic) -> bool {
self.data.equal(&other.data)
}
}

```

Open the linked Rust Anthology page and inspect the generic trait implementation snippet. Compare the marked incorrect expression with the corrected version using the data fields; done means the published example uses the corrected expression and remains valid Rust.
