Debugrepresentation ofserde_yaml::Error0.9.1

API documentation: https://docs.rs/serde_yaml/0.9
Highlights
The
serde_yaml::Valueenum gains aTaggedvariant which represents the deserialization of YAML's!Tagsyntax. Tagged scalars, sequences, and mappings are all supported.An empty YAML input (or document containing only comments) will deserialize successfully to an empty map, empty sequence, or Serde struct as long as the struct has only optional fields. Previously this would error.
A new
.apply_merge()method onValueimplements YAML's<<merge key convention.The
Debugrepresentation ofserde_yaml::Valuehas gotten vastly better (dtolnay/serde-yaml#287).Deserialization of borrowed strings now works.
#[derive(Deserialize, Debug)] struct Struct<'a> { borrowed: &'a str, }let yaml = "borrowed: 'kölcsönzött'\n"; let value: Struct = serde_yaml::from_str(yaml)?; println!("{:#?}", value);
Value's andMapping's methodsgetandget_muthave been generalized to support a &str argument, as opposed to requiring you to allocate and construct aValue::Stringfor indexing into another existingValue.
Mappingexposes more APIs that have become conventional on map data structures, such as.keys(),.values(),.into_keys(),.into_values(),.values_mut(), and.retain(|k, v| …).Breaking changes
Serialization no longer produces leading
---\non the serialized output. You can prepend this yourself if your use case demands it.Serialization of enum variants is now based on YAML's
!Tagsyntax, rather than JSON-style singleton maps.#[derive(Serialize, Deserialize)] enum Enum { Newtype(usize), Tuple(usize, usize, usize), Struct { x: f64, y: f64 }, }
