Challenge Macro - wamp-proto

Macro that allows for default empty implementation of details object on Challenge.

Examples

use wamp_core::messages::{self, Challenge};
use wamp_core::challenge;
use serde_json::json;

// Construct with default empty details object
let mut challenge_message = challenge!("authmethod");
assert_eq!(challenge_message.details, json!({}));

// Construct with custom details
let challenge_message2 = challenge!("authmethod", json!({
    "key": "value"
}));

assert_ne!(challenge_message, challenge_message2);
challenge_message.details = json!({ "key": "value" });
assert_eq!(challenge_message, challenge_message2);

// These macro invocations are the same as the following:
let challenge_message3 = Challenge {
    authmethod: "authmethod".to_string(),
    details: json!({
        "key": "value"
    })
};

assert_eq!(challenge_message, challenge_message3);
assert_eq!(challenge_message2, challenge_message3);
