Struct SelectionChange 

pub struct SelectionChange {
    pub version: u32,
    pub anchor: Position,
    pub active: Position,
}

The selection of a code editor, as the Renderer reported it.

anchor is where the selection started and active where the caret is, so a selection made backwards has the anchor after the active end. Both are read against version, the same series CodeChange counts.

Fields

version: u32

anchor: Position

active: Position
