Function edn_rs::emit_edn

pub fn emit_edn(json: String) -> String

emit_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::emit_edn;

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

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