Struct YamlCodec 

pub struct YamlCodec;

Built-in YAML codec.

Decodes YAML into the canonical Value tree and encodes a value tree back to YAML. Like the TOML codec, the top-level value must be a mapping (the crate’s document contract for config-shaped formats), and a non-mapping top level surfaces as a typed error rather than a panic — on both decode and encode, so round-trips stay symmetric.

Security

Unlike TOML and JSON, YAML supports anchors and aliases, which the parser expands during decode. A small hostile document can therefore reference-expand into a much larger in-memory tree (“billion laughs”). This codec does not itself cap expansion, so callers must decode only size-bounded input — the same trust boundary the other codecs rely on (e.g. rskit-fs bounded reads). Do not feed unbounded or untrusted streams straight into decode_value.
