Description

With format_code_in_doc_comments = true, rustfmt 1.6.0-nightly can format code in line doc comments, but code in block doc comments cannot be formatted.

/// ```rust
/// println!("hello"); // formatted
/// ```

/**
```rust
   println!("hello");          // not formatted
```
*/

fn f() {}
