Struct Placed 

pub struct Placed {
    pub columns: Option<Columns>,
    pub heading: Option<Rect>,
    pub rows: Rect,
    pub map: Option<Rect>,
    pub notice: Option<Rect>,
    pub scroll: usize,
    pub overlay: Option<Rect>,
    pub answers: Option<[Rect; 2]>,
}

Where the last frame put everything a pointer can aim at.

Read back from the layout draw produced rather than described a second time. A hard-coded row-to-y map would be one line out the first time the header or the heading changed height, and being one line out here presses a row nobody chose — on a screen whose keys delete directories.

Default is a frame that was never drawn, on which every press resolves to Spot::Nowhere. That is the honest answer for the first mouse event of a run and for a test that has not painted: a synthetic geometry would be a second layout, which is the thing this type exists to avoid.

Fields

columns: Option<Columns>

The tree’s columns, or None on a frame that drew no tree.

heading: Option<Rect>

The heading line, when the pane was tall enough to spend a row on one.

rows: Rect

The body rows.

map: Option<Rect>

Where the treemap’s image goes, when the pane is up. None is a frame with no map on it, which is every frame in a terminal that cannot draw one.

notice: Option<Rect>

The footer, on a frame where it was saying what just happened. None whenever there is nothing to dismiss — which is what keeps a press on the ordinary footer a miss.

The whole line, though a notice no longer has the whole line to itself: a removal’s position and the session’s freed total share it. Both are figures rather than buttons, so a press that lands on one has nothing of its own to do, and giving it the dismissal beats making a reader aim at a sentence whose length they did not choose.

scroll: usize

Which row of the tree the top drawn row held.

Recorded rather than re-read from the view, so a press maps y to a row through the offset the rows were drawn at — a sync between the frame and the press would otherwise shift every row by the difference.

overlay: Option<Rect>

The topmost overlay’s box, in the ranking super::state::View::overlay uses. One slot, because a press lands on one thing.

answers: Option<[Rect; 2]>

A confirmation’s two answers, in Answer::ALL order, where they were drawn.

Inside overlay and checked first. None whenever no question was on the frame — which is what a press made before the box appeared lands on, and is the whole of what stops such a press from answering one. See super::keymap::finish.
