• async-dropper-simple

  • Missing keywords

    Help users find your crates. Add keywords = ["async-std", "async-drop", "tokio", "async-dropper", "ad-hoc"] (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.

• js-component-bindgen

  • Dependency wasmtime-environ 40.0.2 is significantly outdated

    Upgrade to 41.0.3 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.

  • Dependency wit-bindgen-core 0.52.0 is significantly outdated

    Upgrade to 0.53.1 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.

    wit-bindgen-core versions

  • The Cargo package has no git commit information

    Before publishing a package, make sure all packaged files are committed to the repository, and there are no "dirty" files. Push this commit to crate's public repository.

    To protect against supply chain attacks similar to CVE-2024-3094, lib.rs will soon start flagging non-reproducible packages without public source code as suspicious. Currently only git repositories are supported (but may be hosted anywhere, not just GitHub). If you'd like a different SCM supported, please file a feature request.

  • 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.

  • Failed to verify create's content against its repository

    Verified 30 out of 32 files (includes 2 Cargo-generated).

    • warning: The crates.io package has no commit hash associated with it.
      • Publish a new version, without using --allow-dirty flag. Make sure all changes are committed before publishing. Use include/exclude in Cargo.toml to omit unnecessary files.

    Files in the crates.io crate compared to the repository:

    • Cargo.lock not found.
    • Cargo.toml.orig does not match the repository.
    • js-component-bindgen-1.15.0.crate not found.

    Looked for the crate in crates/js-component-bindgen/. Fetched https://github.com/bytecodealliance/jco.git tagged js-component-bindgen-v1.15.0 (66e11b08c08dc1f128f41ac7247152f6195b13ff).

  • Imprecise dependency requirement tokio = 1

    Cargo does not always pick latest versions of dependencies! Specify the version as tokio = "1.49.0". 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 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").

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

  • Missing categories

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