[Rust APIView] pub use re-export is rendered with invalid `=` syntax

The APIView currently displays this Rust re-export as:

```Rust
pub use Query = query::Query
```

This should be rendered as a standard Rust re-export without `=`:

```Rust
pub use query::Query;
```

The current output is a parser/rendering bug in the Rust language parser, not a guideline issue.

Start by locating the Rust language parser and its APIView rendering logic for public re-exports, then reproduce the issue with the shown `pub use` example. Done means the rendered output is `pub use query::Query;` without the invalid `=` syntax, while other Rust re-exports remain correct.
