Macro plist 

macro_rules! plist {
    ($($plist:tt)+) => { ... };
}

Constructs a plist::Value from a JSON-like literal.

let value = plist!({
    "code": 200,
    "success": true,
    "payload": {
        "features": [
            "serde",
        ]
    }
});

Variables or expressions can be interpolated into the literal. Any type interpolated into an array element or object value must implement the Into<Value> trait, while any type interpolated into a object key must implement Into<String>.

let code = 200;
let features = vec!["serde", "plist"];

let value = plist!({
    "code": code,
    "success": code == 200,
    "payload": {
        features[0]: features[1]
    }
});

Trailing commas are allowed inside both arrays and objects.

let value = plist!([
    "notice",
    "the",
    "trailing",
    "comma -->",
]);
