Macro for creating PEPJSONValue objects with a JSON-like syntax.

Supports marking fields as pseudonyms using pseudonym("value") syntax. Creates an unencrypted PEPJSONValue which can then be encrypted.

Example

use libpep::pep_json;
use serde_json::json;

let pep_value = pep_json!({
    "id": pseudonym("user1@example.com"),
    "age": 16,
    "verified": true,
    "scores": [88, 91, 85]
});

// Then encrypt it
let encrypted = encrypt(&pep_value, &keys, &mut rng);
let decrypted = decrypt(&encrypted, &keys)?;
assert_eq!(decrypted, json!({
    "id": "user1@example.com",
    "age": 16,
    "verified": true,
    "scores": [88, 91, 85]
}));
