Struct Compat 

#[non_exhaustive]
pub struct Compat;

Compatibility presets. Each returns a Settings that can be refined further; presets never change Limits.

Implementations

impl Compat

pub const fn serde_yaml() -> Settings

Behave like serde_yaml for migration: duplicate keys are tolerated (last wins, with a warning), the YAML 1.1 integer forms serde_yaml reads as integers are integers (Settings::yaml11_int_forms: 0b1010, -0x10, +0x10), and output follows serde_yaml’s layout (non-indented sequences, Layout::SerdeYaml), and typed enums read and write newtype variants around numbers, bools, and nulls as tagged scalars (!Square 2.0, Settings::resolve_tagged_variant_content).

The remaining reading differences from serde_yaml are listed, with their reasons, in docs/migrating-from-serde-yaml.md.

A preset is a starting point: refine it like any Settings, here for a docker-compose.yml that relies on merge keys:

use oneyaml_core::{Compat, DuplicateKeys, Layout, Settings};

const COMPOSE: Settings = Compat::serde_yaml().merge_keys(true);

assert_eq!(COMPOSE.get_duplicate_keys(), DuplicateKeys::LastWins);
assert!(COMPOSE.get_yaml11_int_forms() && COMPOSE.get_merge_keys());
assert_eq!(COMPOSE.get_emit().get_layout(), Layout::SerdeYaml);
// Presets never change limits.
assert_eq!(COMPOSE.get_limits(), Settings::new().get_limits());

pub const fn yaml_1_1() -> Settings

Full YAML 1.1 typing: merge keys, 1.1 booleans, legacy octal, sexagesimal numbers, digit separators, and the 1.1 integer forms.
