Struct ListPlan 

pub struct ListPlan {
    pub range: Range<usize>,
    pub lead: f32,
    pub tail: f32,
    pub shift: Option<(f32, f32)>,
    pub first_frame: bool,
}

What a ListSlice comes to: the rows to build, the two spacers’ heights, and the scroll correction the frame needs (see list).

Fields

range: Range<usize>

lead: f32

tail: f32

shift: Option<(f32, f32)>

(drawn, target) on y, for Ui::shift_scroll, when measuring moved the rows; None when nothing needs correcting.

first_frame: bool

Sliced by the window, not a layout: the frame after it has to run.
