Crate yaml_datastore

API for using a set of YAML files as a cohesive datastore.

What this crate supports is having a set of YAML files be accessible as a single, uniform datastore. So for example, if you had a set of YAML files all containing structured data, you could use this crate to query specific values from it. In effect, it’s an ergonomic wrapper for managing a set of files doing the file I/O, and pulling specific elements out of those files.

Usage

Assume there is a set of YAML files under tests/data/, and within exists a file named complete.yaml with the following content:

name: Complete
id: 1
rating: 1.0
complete: true
tags:
  - complete
  - done
  - finished
nested:
  value: true

To access the true contained under nested -> value, you can do the following:

use yaml_datastore::Datastore;

let datastore: Datastore = Datastore::open("tests/data");
let parsed: bool = datastore.get("complete.nested.value").unwrap();
assert!(parsed);

See the Datastore and keypath documentation for more information on how the keypaths are resolved into values.
