Imprecise dependency requirement memchr = 2
Cargo does not always pick latest versions of dependencies! Specify the version as
memchr = "2.7.0". IfCargo.lockends 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 theminimal-versionsflag, 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-versionsCargo 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 = ["…"]to theCargo.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.
Dependency gcc 0.3.22 has issues
It may not be actively developed any more. Consider changing the dependency.
Dependency walkdir 0.1.5 is significantly outdated
Upgrade to 2.5.0 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.Latest stable release is old
It's been over 8 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.
Dependency rl-sys 0.4.1 is a bit outdated
Consider upgrading to 0.5.2 to get all the fixes and improvements.
In Cargo, different 0.x versions are considered incompatible, so this is a semver-major upgrade.

Dependency rustc-hash 1.1.0 is a bit outdated
Consider upgrading to 2.1.0 to get all the fixes and improvements.
Optional dependency 'ramhorns' 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 'ramhorns', 'wgpu', 'bytemuck' may have been unintentional.

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.

Incorrect category
Crate's categories property in
Cargo.tomlcontains 'sorting', which isn't a category we recognizelib.rs has simplified and merged some of crates.io categories. Please file a bug if we got it wrong.

Dependency time 0.1.35 is significantly outdated
Upgrade to 0.3.41 to get all the fixes, and avoid causing duplicate dependencies in projects.
Latest stable release is old
It's been over 9 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?
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.Dependency mrusty 0.3.2 is slightly outdated
Consider upgrading to 1.0.0 to get all the fixes and improvements.
