The example code under type-alias-bounds lint produced two warnings - one from the lint itself and another from the dead_code lint, and only the second one was in the doc. This looked like an error, so I've added `#[allow(dead_code)]` and replaced the example output with the expected one.
[Playground](https://play.rust-lang.org/?version=stable&mode=debug&edition=2018&code=%23%5Ballow(dead_code)%5D%0Atype%20SendVec%3CT%3A%20Send%3E%20%3D%20Vec%3CT%3E%3B)
Some example code that triggers this lint:
```rust
+#[allow(dead_code)]
type SendVec<T: Send> = Vec<T>;
```
This will produce:
```text
-warning: type alias is never used: `SendVec`
- --> src/main.rs:1:1
+warning: bounds on generic parameters are not enforced in type aliases
+ --> src/lib.rs:2:17
|
-1 | type SendVec<T: Send> = Vec<T>;
- | ^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^
+2 | type SendVec<T: Send> = Vec<T>;
+ | ^^^^
|
+ = note: #[warn(type_alias_bounds)] on by default
+ = help: the bound will not be checked when the type alias is used, and should be removed
```
