Summary
serde_yml crate is unsound and unmaintained
Details

Using serde_yml::ser::Serializer.emitter can cause a segmentation fault, which is unsound.

The GitHub project for serde_yml was archived after unsoundness issues were raised.

If you rely on this crate, it is highly recommended switching to a maintained alternative.

Recommended alternatives

  • serde_norway - Maintained fork of serde_yaml, using unsafe-libyaml-norway
  • serde_yaml_ng - Maintained fork of serde_yaml, using unmaintained unsafe-libyaml

Incomplete pure Rust alternatives

These implementation do not rely on C libyaml.
