Struct BreakableMeasure 

pub struct BreakableMeasure<'a> {
    pub full_height: f32,
    pub break_count: &'a mut u32,
    pub extra_location_min_height: &'a mut Option<f32>,
}

Fields

full_height: f32

break_count: &'a mut u32

extra_location_min_height: &'a mut Option<f32>

The minimum height required for any extra locations added to the end. If, for example, there’s a flex with a text element that gets repeated for each location and other flex elements use more locations than this one, the text element will still be drawn on the last location via preferred_break_count and preferred_height. The flex needs to be able to predict the height of the last page so that there isn’t a single element that is higher than the other ones. None here means the element does not use extra locations. This means it is not possible to have an element that does use extra locations, but returns a None height on the last one. Should that ever become necessary we’ll probably have to change this to an Option<Option<f32>>.
