Function package_url 

pub fn package_url(name: &str) -> String

Returns the URL for a coordinate’s page on Maven Central (or maven.google.com for a Google-group coordinate), falling back to a Central search query when name is not a groupId:artifactId pair.

Display link only, never fetched by this process — unlike metadata_urls (a fetch sink), so it is deliberately not gated against a ./.. segment (see deps_core::is_dot_segment’s doc for the fetch-sink-vs-display-link scope split, #379).
