• virtiofsd

  • Dependency env_logger 0.8.4 is significantly outdated

    Upgrade to 0.11.8 to get all the fixes, and avoid causing duplicate dependencies in projects.

    In Cargo, different 0.x versions are considered incompatible, so this is a semver-major upgrade.

    env_logger versions

  • Dependency bitflags 1.2 is outdated

    Upgrade to 2.9.0 to get all the fixes, and avoid causing duplicate dependencies in projects.

    Easy way to bump dependencies: cargo install cargo-edit; cargo upgrade -i; Also check out Dependabot service on GitHub.

    bitflags versions

  • Dependency libseccomp-sys 0.2 is a bit outdated

    Consider upgrading to 0.3.0 to get all the fixes and improvements.

  • Dependency syslog 6.1 is outdated

    Upgrade to 7.0.0 to get all the fixes, and avoid causing duplicate dependencies in projects.

  • Imprecise dependency requirement clap = 4

    Cargo does not always pick latest versions of dependencies! Specify the version as clap = "4.5.38". 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.

  • Missing categories

    Categories improve browsing of lib.rs and crates.io. Add categories = ["filesystem"] to the Cargo.toml.

    Even if there are no categories that fit precisely, pick one that is least bad. You can also propose new categories in crates.io issue tracker.

  • Missing keywords

    Help users find your crates. Add keywords = ["inode", "handle", "daemon", "flags", "mnt"] (up to 5) to the Cargo.toml. Best keywords are alternative terms or their spellings that aren't in the name or description. Also add a keyword that precisely categorizes this crate and groups it with other similar crates.

  • Using outdated edition for no reason

    We estimate that this crate requires at least Rust 1.77, which is newer than the last 2018-edition compiler. You can upgrade without breaking any compatibility. Run cargo fix --edition and update edition="…" in Cargo.toml.

    Using the latest edition helps avoid old quirks of the compiler, and ensures Rust code has consistent syntax and behavior across all projects.

  • Dependency vmm-sys-util 0.12.1 is outdated

    Upgrade to 0.13.0 to get all the fixes, and avoid causing duplicate dependencies in projects.

  • docs.rs build failed

    docs.rs site failed to build the crate, so users will have trouble finding the documentation. Docs.rs supports multiple platforms and custom configurations, so you can make the build work even if normal crate usage has special requirements.

    Docs.rs doesn't need to run or even link any code, so system dependencies can simply be skipped. You can also set cfg() flags just for docs.rs and use them to hide problematic code.
