• eyre

  • Dependency pyo3 ^0.20 is significantly outdated

    Upgrade to 0.29.0 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.

  • Missing keywords

    Help users find your crates. Add keywords = ["error-handling", "report", "backtrace", "built", "object"] (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.

• eyre, color-eyre, color-spantrace, btparse

  • Using outdated edition for no reason

    We estimate that this crate requires at least Rust 1.65, 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.

  • Optional dependency 'color-spantrace' exposed as an implicit feature

    Cargo automatically makes publicly-available crate features for every optional dependency, unless the dependencies are referenced using dep: syntax. Features 'color-spantrace', 'tracing-error', 'url' may have been unintentional.

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

  • 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.

  • 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.
