Struct ManifestQuery 

pub struct ManifestQuery;

Query engine for extracting subtrees from manifest YAML values.

Implementations

impl ManifestQuery

pub fn query( root: &Value, path: &str, manifest_id: &str, ) -> Result<Value, NapError>

Traverse a dot-separated path into a YAML value tree.

Arguments

• root — The YAML value to traverse (typically a serialized Manifest).
• path — Dot-separated path. e.g., "references.appears_in".

Returns

The subtree at the given path, or an error if any segment is missing.

Examples

use serde_yaml::Value;
use nap_core::query::ManifestQuery;

let yaml = "
name: Luke Skywalker
properties:
  homeworld: tatooine
  species: human
";
let root: Value = serde_yaml::from_str(yaml).unwrap();
let result = ManifestQuery::query(&root, "properties.homeworld", "test").unwrap();
assert_eq!(result, Value::String("tatooine".to_string()));

pub fn list_keys( root: &Value, path: &str, manifest_id: &str, ) -> Result<Vec<String>, NapError>

List available keys at a given path (for introspection / tab-completion).
