Bump serde_yaml from 0.8.26 to 0.9.2

[dependabot]

Bumps serde_yaml from 0.8.26 to 0.9.2.

Release notes

Sourced from serde_yaml's releases.

0.9.2

• Improve Debug representation of serde_yaml::Error

0.9.1

• Fix panic on some documents containing syntax error (#293)
• Improve error messages that used to contain duplicative line/column information (#294)

0.9.0

API documentation: https://docs.rs/serde_yaml/0.9

Highlights

• The serde_yaml::Value enum gains a Tagged variant which represents the deserialization of YAML's !Tag syntax. 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 on Value implements YAML's << merge key convention.

• The Debug representation of serde_yaml::Value has 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 and Mapping's methods get and get_mut have been generalized to support a &str argument, as opposed to requiring you to allocate and construct a Value::String for indexing into another existing Value.

• Mapping exposes 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 ---\n on the serialized output. You can prepend this yourself if your use case demands it.

• Serialization of enum variants is now based on YAML's !Tag syntax, rather than JSON-style singleton maps.

  #[derive(Serialize, Deserialize)]
  enum Enum {
      Newtype(usize),
      Tuple(usize, usize, usize),
      Struct { x: f64, y: f64 },
  }
