I am trying to learn layout in iced and ran across the grid widget. I would like to use it but am having a problem. In the example below I get the error "consider specifying the generic arguments '::<Message, Theme, Renderer>`. I do not know how to do this. Any input will be appreciated.

widget::grid::Grid::from_vec(
    // consider specifying the generic arguments: `::<Message, Theme, Renderer>`
    vec![       
        widget::text("Cell 1:1").into(),
        widget::text("Cell 1:2").into(),
        widget::text("Cell 2:1").into(),
        widget::text("Cell 2:2").into(), 
    ]  
)
.columns(2);
