Function rustdoc::passes::collect_intra_doc_links::resolution_failure

fn resolution_failure(
    collector: &mut LinkCollector<'_, '_>,
    diag_info: DiagnosticInfo<'_>,
    path_str: &str,
    disambiguator: Option<Disambiguator>,
    kinds: SmallVec<[ResolutionFailure<'_>; 3]>
) -> Option<(Res, Option<DefId>)>

Reports a link that failed to resolve.

This also tries to resolve any intermediate path segments that weren’t handled earlier. For example, if passed Item::Crate(std) and path_str std::io::Error::x, this will resolve std::io::Error.
