Macro dict 

macro_rules! dict {
    ($($key:tt: $value:expr),* $(,)?) => { ... };
}

Constructs typed Dictionary<K, V> literals, close to Godot’s own syntax.

Any value can be used as a key, but to use an expression you need to surround it in () or {}.

Type annotation

The macro creates a typed Dictionary<K, V>. You must provide an explicit type annotation to specify K and V. Keys must implement AsArg<K> and values must implement AsArg<V>.

Example

use godot::builtin::{dict, Dictionary, GString, Variant};

// Type annotation required
let d: Dictionary<GString, i64> = dict! {
    "key1": 10,
    "key2": 20,
};

// Works with Variant values too
let d: Dictionary<GString, Variant> = dict! {
    "str": "Hello",
    "num": 23,
};
