Code reviews of the icu_provider crate // Lib.rs

These reviews are from cargo-vet. To add your review, set up cargo-vet and submit your URL to its registry.

The current version of icu_provider is 2.0.0-beta1.

1.5.0 (older version) safe-to-run, does-not-implement-crypto

From google/supply-chain copy of chromium. By George Burgess IV.

This crate contains a custom impl of FxHash. The maintainers needed a custom hashing function that was const and self-contained. Since FxHash isn't built to be crypto secure, this does-not-implement-crypto.

1.5.0 (older version) safe-to-deploy

From mozilla/supply-chain copy of hg. Audited without comment by Makoto Kato.

cargo-vet does not verify reviewers' identity. You have to fully trust the source the audits are from.

safe-to-run

This crate can be compiled, run, and tested on a local workstation or in controlled automation without surprising consequences. More…

does-not-implement-crypto (implies crypto-safe)

Inspection reveals that the crate in question does not attempt to implement any cryptographic algorithms on its own.

Note that certification of this does not require an expert on all forms of cryptography: it's expected for crates we import to be "good enough" citizens, so they'll at least be forthcoming if they try to implement something cryptographic. When in doubt, please ask an expert.

crypto-safe

Implied by other criteria

All crypto algorithms in this crate have been reviewed by a relevant expert.

Note: If a crate does not implement crypto, use does-not-implement-crypto, which implies crypto-safe, but does not require expert review in order to audit for.

safe-to-deploy (implies safe-to-run)

This crate will not introduce a serious security vulnerability to production software exposed to untrusted input. More…

Lib.rs has been able to verify that all files in the crate's tarball are in the crate's repository. Please note that this check is still in beta, and absence of this confirmation does not mean that the files don't match.

Crates in the crates.io registry are tarball snapshots uploaded by crates' publishers. The registry is not using crates' git repositories, so there is a possibility that published crates have a misleading repository URL, or contain different code from the code in the repository.

To review the actual code of the crate, it's best to use cargo crev open icu_provider. Alternatively, you can download the tarball of icu_provider v2.0.0-beta1 or view the source online.
