  • Imprecise dependency requirement serde = 1

    Cargo does not always pick latest versions of dependencies! Specify the version as serde = "1.0.219". 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.

    This crate does not bump semver-minor when adding new features, so to be safe you get all the features/APIs/fixes that your crate depends on, require a more specific patch version.

  • Needs to specify correct MSRV

    We estimate that this crate requires at least Rust 1.60, but specified Rust 1.56 as the minimum version. Add rust-version = "1.60" to the Cargo.toml.

    markdown versions

  • Using outdated edition for no reason

    We estimate that this crate requires at least Rust 1.60, 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.

• mdxjs

  • Dependency markdown =1.0.0-alpha.22 is significantly outdated

    Upgrade to 1.0.0-alpha.23 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.

  • Imprecise dependency requirement rustc-hash = 2

    Cargo does not always pick latest versions of dependencies! Specify the version as rustc-hash = "2.1.0". 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.

  • Optional dependency 'serde' exposed as an implicit feature

    Cargo automatically makes publicly-available crate features for every optional dependency, unless the dependencies are referenced using dep: syntax. Feature 'serde' may have been unintentional.

  • Using outdated edition for no reason

    We estimate that this crate requires at least Rust 1.81, 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.

  • Latest stable release is old

    It's been over 4 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").

    It's an opportunity to update it to the current Rust edition.

  • Missing categories

    Categories improve browsing of lib.rs and crates.io. Add categories = ["algorithms"] 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.

  • README missing from crate tarball

    Cargo sometimes fails to package the README file. Ensure the path to the README in Cargo.toml is valid, and points to a file inside the crate's directory.

• mdast_util_to_markdown

  • Missing categories

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

    List of available categories

  • No repository property

    Specify git repository URL in Cargo.toml to help users find more information, contribute, and for lib.rs to read more info.

  • No readme property

    Specify path to a README file for the project, so that information about is included in the crates.io tarball.

  • 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.

  • Missing keywords

    Help users find your crates. Add keywords = ["markdown", "ast", "mdast-util-to-markdown"] (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.

If some of these crates are unmaintained and shouldn't be checked, yank them or add [badges.maintenance]
status = "deprecated" to their Cargo.toml.
