0.2.5 (older version) safe-to-deploy

From mozilla/supply-chain copy of hg. By Aria Beingessner.

I own this crate, and most of its versions were codeveloped and reviewed by Nika Layzell. This version was not explicitly reviewed by her, but it was specifically a release that made the code pass miri and was reviewed by me. Firefox uses it in the gecko-ffi configuration which is less thoroughly tested and more dangerous but we're reasonably confident in it. The real danger is from C++ code failing to use it correctly in FFI but that's just how FFI is.

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

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 thin-vec. Alternatively, you can download the tarball of thin-vec v0.2.13 or view the source online.
