Examples

let empty_tree = tree_v7400! {};

let tree = tree_v7400! {
    Node0: {
        Node0_0: {}
        Node0_1: {}
    }
    Node1: {
        // You can use trailing comma.
        Node1_0: {},
        Node1_1: {},
    }
    // Use parens to specify attributes by single array.
    // Note that the expression inside parens should implement
    // `IntoIterator<Item = AttributeValue>`.
    Node2: (vec!["hello".into(), "world".into(), 42i32.into()]) {}
    // Use brackets to specify attributes one by one.
    Node3: ["hello", "world", 3.14f32, &b"BINARY"[..]] {}
