Code review of the comedy crate // Lib.rs

This review is from cargo-vet. To add your review, set up cargo-vet and submit your URL to its registry.

From mozilla/supply-chain copy of hg. By Nick Alexander.

The comedy crate was written by Adam Gashlin for Mozilla's use. The entire comedy 0.2.0 crate is full of unsafe code and makes many assumptions about memory and layout, but there is no particular processing of untrusted input here.

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

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

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

safe-to-run

Implied by other criteria

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

Lib.rs has been able to verify that all files in the crate's tarball are in the crate's repository with a git tag matching the version. 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 comedy. Alternatively, you can download the tarball of comedy v0.2.0 or view the source online.
