}

Using master revision, 1d8491b (Jan 24 2023).

cat a.rs | cargo run --bin rustfmt -- --config format_code_in_doc_comments=true

Converts // comments to /* comments.

struct Scope {
    free: u32, /* abracadabra long long very long very very long comment comment comment hello world */
}

However, short comments are preserved as // comments.
