YAML Hash with merge/update capabilities

Wrapper around yaml_rust::yaml::Hash, which is a type alias for linked_hash_map::LinkedHashMap

NOTE: Highly recommend using yaml-hash instead of this crate since it uses yaml-rust2 versus the unmaintained yaml-rust. Also, it provides additional functionality, including recursive get value via dotted key.

Example

use merge_yaml_hash::{MergeYamlHash, Yaml};

let mut hash = MergeYamlHash::new();

// Merge YAML data from strings
hash.merge("apple: 1\nbanana: 2");
hash.merge("cherry:\n  sweet: 1\n  tart: 2");
assert_eq!(
    hash.to_string(),
    "apple: 1\nbanana: 2\ncherry:\n  sweet: 1\n  tart: 2",
);

// Merge YAML data from file
// * Note that insertion order is maintained
hash.merge("tests/c.yaml"); // "banana: 3"
assert_eq!(
    hash.to_string(),
    "apple: 1\nbanana: 3\ncherry:\n  sweet: 1\n  tart: 2",
);
