This is a Bytecode Alliance authored crate maintained in the regalloc2 repository of which I'm one of the maintainers and publishers for. I am employed by a member of the Bytecode Alliance and plan to continue doing so and will actively maintain this crate over time.

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 regalloc2. Alternatively, you can download the tarball of regalloc2 v0.11.0 or view the source online.
