I prefer data as is rather than having to double guess every search result

What’s the bad scenario you’re worried about here? What type of data you’re specifically worried about? Do you expect me to maliciously manipulate the data, or is even well-intentioned curation and use of heuristics somehow not acceptable?

My view on data cleanup is probably very different than other people’s, because I’ve spent a lot (likely too much) time with the crates’ data. The pure unadulterated source data is… bad. It’s very sparse (most crates don’t fill it in). It’s full of outdated information (set once and forgotten, wrong for forks). Some crates-io category slugs are pretty misleading, so tons of crates are miscategorized by their own authors: parsing is not for file parsers, database is not for databases. accessibility …I can’t even. Who put ogg parsers, gRPC, garrysmod, RFID readers in there?

There are tons of name-squatted crates, ferris guessing games, or just people’s baby steps in Rust. If you search on crates.io you often get the pure data of someone publishing a crate years ago and forgetting about it. This is pure, this is ranked objectively, this is curated and subjective.

crates-io shows you plainly only the license of the crate you’re looking at. lib.rs goes further and checks if the crate has any dependencies which are GPL, because if a crate says it’s MIT but has GPL deps, it actually is GPL.

crates-io shows you repository URL exactly as-is specified in the metadata, which could be inaccurate (in case of forks) or outright fake (someone else’s repo). lib.rs checks if the repository URL actually contains the crate or has the same owner as the crate, and will add a link to the true source code if the repo url is suspicious.

crates-io shows owners’ names from the free-form name field, so somebody malicious could pretend to be a well-known trusted user. lib.rs only allows display names for established/reputable accounts, and uses login name for new/untrusted accounts.
