new

The new keyword allocates and constructs a new instance of a type, invoking its constructor and returning the new object.

Syntax & Example​

class Vec2 {
    x: f64,
    y: f64,
}

let v = new Vec2 { x: 1.0, y: 2.0 };

Use Cases​

  • Explicitly allocating a new instance of a class or reference type.
  • Invoking a constructor with initial field values.
  • Distinguishing heap-allocated construction from struct literals.
