Enum Zone 

pub enum Zone {
    Mark,
    Open,
    Name,
}

Which part of a row the pointer is on.

pristine’s rows carry a target pua’s do not: the mark box. A box that is drawn and cannot be pressed is a lie the pointer tells about itself, so it is a zone of its own rather than part of the name.

Variants

Mark

The [x] box — mark this row’s subtree, or unmark it.

Open

The ▸/▾ indicator — open the row, or close it.

A leaf leaves this cell blank, and a blank cell cannot have been aimed at: opening a row with nothing under it is a no-op in super::state::View rather than a case the hit test has to know about.

Name

The indent, the name, and everything past it — put the cursor here.
