Enum Gesture 

pub enum Gesture {
    Aim,
    Click,
    Double,
    Wheel(Motion),
}

What the loop has judged one mouse event to be.

Judgements about previous events, which the one in hand cannot see — whether a press has already moved, whether one landed on this spot a moment ago — so they are made by [super::Pointer] and handed here. That keeps pointer() a pure function of one gesture and one spot, which is what makes the whole table assertable without a terminal.

Variants

Aim

A press, or the pointer merely passing over. It aims and no more.

The rule the deferred click forced: at the moment the button goes down there is no way to tell a click from a drag, so a press that acted would re-sort the tree under a hand that was about to select from it. See finish.

Click

A press and a release, with no movement between them — the click, at last.

Double

Two clicks on one row, close enough together to be one gesture.

Wheel(Motion)

One turn of the wheel.

The direction belongs to the action rather than to the row of the table: the wheel does the same thing over a spot whichever way it turns, so both turns are one row and Gesture::same is what keys them together.
