Struct Line 

pub struct Line {
    pub at: Pos,
    pub len: u16,
    pub orientation: Orientation,
    pub stroke: Stroke,
}

A line: a position, a length, an orientation and a stroke. It names no glyph of its own — an end is one arm in the line’s stroke, not a chosen glyph, because an end has to say where the stroke stops and what may join it there, which an arm does and a literal cannot: a literal composes as a cell with four Closed arms, so nothing connects into it and two lines meeting at a shared end could never make the corner they make.

A complete shape in the sense of Complete and fragment in docs/model.md. No minimum length is declared: a length of 0 draws nothing, a length of 1 draws its one position as an end, and neither is rejected.

Fields

at: Pos

The position of the line’s first cell.

len: u16

How many cells the line occupies. Any value is accepted, including 0.

orientation: Orientation

Whether the line runs along a row or a column.

stroke: Stroke

The stroke every cell this line writes is drawn in.
