Function tpnote_lib::html::rewrite_links

pub fn rewrite_links(
    html: String,
    prepend_dirpath: &Path,
    rewrite_ext: bool,
    allowed_urls: Arc<RwLock<HashSet<PathBuf>>>
) -> String

Helper function that scans the input html string and converts all relative local HTML links to absolute links by prepending prepend_dirpath. If prepend_dirpath is empty, no convertion is perfomed. Local absolute links and external URLs always remain untouched. If rewrite_ext is true and the link points to a known Tp-Note file extension, then .html is appended to the converted link. The resulting HTML string contains all rewritten links, whose targets are finally added to the allowed_urls.
