Dependency bitfield 0.17.0 is significantly outdated
Upgrade to 0.19.4 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.
Dependency object 0.36.0 is significantly outdated
Upgrade to 0.39.1 to get all the fixes, and avoid causing duplicate dependencies in projects.
Dependency serde_yaml 0.9 has issues
It may not be actively developed any more. Consider changing the dependency.
Dependency indicatif 0.17 is outdated
Upgrade to 0.18.4 to get all the fixes, and avoid causing duplicate dependencies in projects.
Dependency rand 0.8 is outdated

Dependency scroll 0.12.0 is outdated
Upgrade to 0.13.0 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 = "4.6.0". 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.

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.

Missing categories
Categories improve browsing of lib.rs and crates.io. Add
categories = ["embedded", "hardware-support"]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.
Missing keywords
Help users find your crates. Add
keywords = ["peripheral-access-crate", "mcu", "py32"](up to 5) to theCargo.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.Optional dependency 'cortex-m-rt' 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 'cortex-m-rt' may have been unintentional.

Latest stable release is old
It's been over 20 months. 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").Nightly crates tend to have a short lifespan. We're delisting them if they're not updated frequently.
Imprecise dependency requirement syn = 2
Cargo does not always pick latest versions of dependencies! Specify the version as
syn = "2.0.117". 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.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.

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.

This is most likely to happen when using theminimal-versionsflag, used by users of old Rust versions.Using outdated edition for no reason
We estimate that this crate requires at least Rust 1.59, which is newer than the last 2018-edition compiler. You can upgrade without breaking any compatibility. Run
cargo fix --editionand updateedition="…"inCargo.toml.Using the latest edition helps avoid old quirks of the compiler, and ensures Rust code has consistent syntax and behavior across all projects.

Crate is 'reserved'
Please be respectful of crates.io and don't squat crate names.
It's OK if you intend to publish this project in the near future. Keep in mind that even if you have good intentions, things may not go as planned. crates.io won't reclaim abandoned crates, so reserving good names may end up wasting the good names.
