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](https://crates.io/crates/serde norway) - Maintained fork of serde yaml, using unsafe-libyaml-norway
• [serde yaml ng](https://crates.io/crates/serde yaml ng) - Maintained fork of serde yaml, using unmaintained unsafe-libyaml

Incomplete pure Rust alternatives

These implementation do not rely on C libyaml.

• [serde yaml2](https://crates.io/crates/serde yaml2)
• yaml-peg
