Struct Item

pub struct Item {
    pub real: Point,
    pub ghost: Option<Point>,
    pub part: Part,
}

An element of a Text

This struct is comprised of three parts:

• A real Point, representing a position on the real Text;
• A ghost Point, which is a position in a Ghost, None if not in a Ghost;
• A Part, which will either be a char or a Tag;

Fields

real: Point

The real Point

ghost: Option<Point>

The Point in a Ghost

If there are multiple Ghosts in the same byte, this Point will point to a sum of the previous Text’s lengths plus the position on this specific Ghost, so every Point should point to a specific position in a byte.

part: Part

A Part, which will either be a char or a Tag;

Implementations
