Enum alacritty::selection::Selection

        region: Range<Point<isize>>,

Describes a region of a 2-dimensional area

Used to track a text selection. There are three supported modes, each with its own constructor: simple, semantic, and lines. The simple mode precisely tracks which cells are selected without any expansion. semantic mode expands the initial selection to the nearest semantic escape char in either direction. lines will always select entire lines.

Calls to [update] operate different based on the selection kind. The simple mode does nothing special, simply tracks points and sides. semantic will continue to expand out to semantic boundaries as the selection point changes. Similarly, lines will always expand the new point to encompass entire lines.

Variants

Simple

Fields of Simple

region: Range<Anchor>

The region representing start and end of cursor movement

Semantic

Fields of Semantic

region: Range<Point<isize>>

The region representing start and end of cursor movement

Lines

Fields of Lines

region: Range<Point<isize>>

The region representing start and end of cursor movement

initial_line: isize

The line under the initial point. This is always selected regardless of which way the cursor is moved.
