Release Notes

dtolnay/serde-yaml (serde_yaml)

`v0.9.34`

As of this release, I am not planning to publish further versions of serde_yaml as none of my projects have been using YAML for a long time, so I have archived the GitHub repo and marked the crate deprecated in the version number. An official replacement isn't designated for those who still need to work with YAML, but https://crates.io/search?q=yaml\&sort=relevance and https://crates.io/keywords/yaml has a number of reasonable-looking options available.

`v0.9.33`

Fix quadratic parse time for YAML containing deeply nested flow collections (https://github.com/dtolnay/unsafe-libyaml/issues/26)

`v0.9.32`

Fix unused_imports warnings when compiled by rustc 1.78

`v0.9.31`

Add swap_remove and shift_remove methods on Mapping (#408)

`v0.9.30`

Update proc-macro2 to fix caching issue when using a rustc-wrapper such as sccache

`v0.9.29`

Turn on deny(unsafe_op_in_unsafe_fn) lint

`v0.9.28`

Update unsafe-libyaml dependency to pull in unaligned write fix

`v0.9.27`

Always serialize serde_yaml::Number containing NaN as a positive NaN (#394)

`v0.9.26`

Guarantee that .nan is deserialized as a positive NaN (#392, #393)

`v0.9.25`

Serialize using quoted style around scalar that has digits with leading zero (#347)

`v0.9.24`

Implement FromStr for serde_yaml::Number (#381)

`v0.9.23`

Documentation improvements

`v0.9.22`

Update indexmap dependency to version 2

`v0.9.21`

Make Tag::new panic if given empty string, since YAML has no syntax for an empty tag

`v0.9.20`

Allow an empty YAML document to deserialize to None or Value::Null, in addition to the previously supported empty vector, empty map, and struct with no required fields

`v0.9.19`

Fix message duplication between serde_yaml::Error's Display and source() (#359, #360)

`v0.9.18`

Add support for emitting Unicode characters over codepoint U+FFFF (#356)

`v0.9.17`

Improve Debug representation of some error messages

`v0.9.16`

Opt out of -Zrustdoc-scrape-examples on docs.rs for now

`v0.9.15`

Documentation improvements

`v0.9.14`

Implement Deserializer for TaggedValue and &TaggedValue (#339)

`v0.9.13`

Recognize True, TRUE, False, FALSE as booleans, Null, NULL as null (#330)

`v0.9.12`

Support deserializing tagged literal scalar into primitive (#327)
```
"foo": !!int |-
  7200
```

`v0.9.11`

Serialize strings on a single line when they do not already contain a newline character, regardless of string length (#321, #322)

`v0.9.10`

Make Display for Number produce the same representation as serializing (#316)

`v0.9.9`

Add serde_yaml::with::singleton_map_recursive

`v0.9.8`

Fix serialization of TaggedValue when used with to_value (#313)

`v0.9.7`

Allow an empty plain scalar to deserialize as an empty map or seq (#304)

`v0.9.6`

Fix tag not getting serialized in certain map values (#302)

`v0.9.5`

Implement Display trait for serde_yaml::value::Tag (#307, thanks @masinc)

`v0.9.4`

Add serde_yaml::with::singleton_map for serialization of enums as a 1-entry map (#300)
Reject duplicate keys when deserializing Mapping or Value (#301)

`v0.9.3`

Add categories to crates.io metadata
Add keywords to crates.io metadata

`v0.9.2`

Improve Debug representation of serde_yaml::Error

`v0.9.1`

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

`v0.9.0`

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 (https://github.com/dtolnay/serde-yaml/pull/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 },
}

- !Newtype 1
- !Tuple [0, 0, 0]
- !Struct {x: 1.0, y: 2.0}

A bunch of non-base-10 edge cases in number parsing have been resolved. For example 0x+1 and ++0x1 are now parsed as strings, whereas they used to be incorrectly treated as numbers.

Deserializers obtained through iteration can no longer be iterated further:

let deserializer = serde_yaml::Deserializer::from_str(multiple_documents);
for de in deserializer {
    // correct:
    let myvalue = T::deserialize(de)?;

    // incorrect: used to produce some questionable result, now produces 0 sub-documents
    for questionable in de {
        let wat = T::deserialize(questionable)?;
    }
}

The abandoned yaml-rust crate is no longer used as the YAML backend. The new libyaml-based backend surely has different edge cases and quirks than yaml-rust.
Some excessive PartialEq impls have been eliminated.
The serde_yaml::to_vec function has been removed. Use serde_yaml::to_writer for doing I/O, or use serde_yaml::to_string + .into_bytes() on the resulting String.
The serde_yaml::seed module has been removed. Now that a serde_yaml::Deserializer is publicly available, the same use cases can be addressed via seed.deserialize(Deserializer::from_str(…)) instead.

Bugfixes

Empty values in a mapping are supported, and deserialize to empty string when the corresponding struct field is of type string. Previously they would deserialize to "~" which makes no sense.
128-bit integer deserialization now supports hex and octal input.
Serde_yaml now includes a mitigation against a "billion laughs" attack in which malicious input involving YAML anchors and aliases is used to consume an amount of processing or memory that is exponential in the size of the input document. Serde_yaml will quickly produce an error in this situation instead.
