pub struct SpriteBatch {
pub vertices: Vec<SpriteVertex>,
}Expand description
精灵批次命令
收集同一纹理的精灵，按 z-order 排序后批量绘制。
Fields§
§vertices: Vec<SpriteVertex>精灵顶点数据（6 个顶点 = 2 三角形 / 精灵）

then be further downcast into Box<ConcreteType> where ConcreteType implements Trait.Source§fn into_any_rc(self: Rc<T>) -> Rc<dyn Any>
