Struct Offset 

pub struct Offset {
    pub x: u16,
    pub y: u16,
}

A position inside one window, counted from its top-left corner.

Not the same thing as a Pos, and kept apart for the same reason the two conventions a cell carries are: a Pos is a point in the plane and may be negative, an Offset is a column and a row within a rectangle and never is. Which one a method takes is the question it is asking — a figure is placed at a Pos, a click arrives as an Offset — so the two are separate types rather than one rectangle’s worth of interchangeable numbers.

Fields

x: u16

Grows to the right, from the window’s own leftmost column.

y: u16

Grows downward, from the window’s own topmost row.
