  = ID: RUSTSEC-2020-0091
  = Advisory: https://rustsec.org/advisories/RUSTSEC-2020-0091
  = Using the `arc_swap::access::Map` with the `Constant` test helper (or with
    user-provided implementation of the `Access` trait) could sometimes lead to the
    map returning dangling references.

    Replaced by implementation without `unsafe`, at the cost of added `Clone` bound
    on the closure and small penalty on performance.
  = Announcement: https://github.com/vorner/arc-swap/issues/45
  = Solution: Upgrade to >=1.1.0 OR >=0.4.8
