Macro vslice 

macro_rules! vslice {
    ($($elements:expr),* $(,)?) => { ... };
}

Constructs a slice of Variant literals, useful for passing to vararg functions.

Many APIs in Godot have variable-length arguments. GDScript can call such functions by simply passing more arguments, but in Rust, the parameter type &[Variant] is used.

This macro creates a slice of Variant values.

Examples

Variable number of arguments

let slice: &[Variant] = vslice![42, "hello", true];
let concat: GString = godot::global::str(slice);

In practice, you might want to use godot_str! instead of str().

Dynamic function call via reflection

NIL can still be passed inside vslice!, just use Variant::nil().

let mut obj: Gd<Object> = some_object();

obj.call("some_method", vslice![
    Vector2i::new(1, 2),
    Variant::nil(),
]);

To create typed and untyped Arrays, use the array! and varray! macros respectively.

For dictionaries, a similar macro vdict! exists.
