  • Dependency structopt 0.3 has issues

    It has been losing active users, which may be a sign it's deprecated or obsolete. Consider replacing it with a different crate.

  • Imprecise dependency requirement regex = 1

    Cargo does not always pick latest versions of dependencies! Specify the version as regex = "1.11.0". If Cargo.lock ends up having an unexpectedly old version of the dependency, you might get a dependency that lacks features/APIs or important bugfixes that you depend on. This is most likely to happen when using the minimal-versions flag, used by users of old Rust versions.

    If you want to keep using truly minimal dependency requirements, please make sure you test them in CI with -Z minimal-versions Cargo option, because it's very easy to accidentally use a feature added in a later version.

  • Latest stable release is old

    It's been over 3 years. Is this crate still maintained? Make a new release, either to refresh it, or to set

    [badges.maintenance]
    status = "deprecated"
    

    (or "as-is", "passively-maintained").

    If the crate is truly stable, why not make a 1.0.0 release?
