Function edn_rs::json_to_edn

pub fn json_to_edn(json: String) -> String

json_to_edn receives a json string and parses its common key-values to a regular EDN format. tested examples are:

1. "{\"hello world\": \"julia\"}" becomes "{:hello-world \"julia\"}"
2. "{\"hello\": null}" becomes "{:hello nil}"
3. {\"hello\": 'c'} becomes "{:hello \\c}"
4. "{\"multi_string with underscore\": 545643}" becomes "{:multi-string-with-underscore 545643}"

use edn_rs::json_to_edn;

fn emits_helloworld_edn() {
    let json = String::from("{\"hello\": \"world\"}");
    let edn = String::from("{:hello \"world\"}");

    assert_eq!(edn, json_to_edn(json));
}

fn emits_vec_of_map_edn() {
    let json = String::from("[{\"hello\": \"world\"}, {\"hello\": \"julia\"}, {\"hello\": \"serde\"}");
    let edn = String::from("[{:hello \"world\"} {:hello \"julia\"} {:hello \"serde\"}]");

    assert_eq!(edn, json_to_edn(json));
}
