pub(crate) fn implicit_details_from_attrs(attrs: &[Attribute]) -> Option<String>Expand description
Extract the implicit details from doc attributes (paragraphs 3+).
In roxygen2, paragraph 1 is the title, paragraph 2 is the description,
and paragraphs 3+ become \details{}. This function skips paragraphs 1 and 2
and returns the remaining free-form paragraphs (before the first @tag)
joined with \n\n.
Returns None if there are fewer than 3 paragraphs, no doc comments, or if
docs start with a @tag.
