Crate yaml_rust2

YAML 1.2 implementation in pure Rust.

Usage

This crate is on github and can be used by adding yaml-rust2 to the dependencies in your project’s Cargo.toml.

[dependencies]
yaml-rust2 = "0.9.0"

Examples

Parse a string into Vec<Yaml> and then serialize it as a YAML string.

use yaml_rust2::{YamlLoader, YamlEmitter};

let docs = YamlLoader::load_from_str("[1, 2, 3]").unwrap();
let doc = &docs[0]; // select the first YAML document
assert_eq!(doc[0].as_i64().unwrap(), 1); // access elements by index

let mut out_str = String::new();
let mut emitter = YamlEmitter::new(&mut out_str);
emitter.dump(doc).unwrap(); // dump the YAML object to a String

Features

Note: With all features disabled, this crate’s MSRV is 1.65.0.

encoding (enabled by default)

Enables encoding-aware decoding of Yaml documents.

The MSRV for this feature is 1.70.0.

The MSRV for this feature is 1.70.0.
