    "summary": "The [repository](https://github.com/dtolnay/unsafe-libyaml) was archived by its owner on 2024-03-25 and is read-only. The last release is 0.2.11 (March 2024). `unsafe-libyaml` is a machine translation of libyaml's C code into unsafe Rust (c2rust). Bugs found in it will not be fixed upstream. It is used by `serde_yaml` (itself deprecated) and by forks such as `serde_yaml_ng`. ## Alternatives Consider a YAML parser written in safe Rust, for example: - [saphyr](https://crates.io/crates/saphyr) ([serde-saphyr](https://crates.io/crates/serde-saphyr) for serde users) - [noyalib](https://crates.io/crates/noyalib)",
