Convert JSON to YAML.

Marshals the object into JSON then converts JSON to YAML and returns the YAML.

Unmarshal converts YAML to JSON then uses JSON to unmarshal into an object, optionally configuring the behavior of the JSON unmarshal.

UnmarshalStrict is like Unmarshal except that any mapping keys that are duplicates will result in an error.

YAMLToJSON converts YAML to JSON.

YAMLToJSONStrict is like YAMLToJSON but enables strict YAML decoding, returning an error on any duplicate field names.

JSONOpt is a decoding option for decoding from JSON format.
