Struct alacritty_terminal::selection::Selection

pub struct Selection {
    pub ty: SelectionType,
    // some fields omitted
}

Describes a region of a 2-dimensional area.

Used to track a text selection. There are four supported modes, each with its own constructor: simple, block, semantic, and lines. The simple mode precisely tracks which cells are selected without any expansion. block will select rectangular regions. 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 and block mode do nothing special, simply track 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.

Implementations

impl Selection

pub fn new(ty: SelectionType, location: Point<usize>, side: Side) -> Selection

pub fn update(&mut self, point: Point<usize>, side: Side)

Update the end of the selection.

    delta: isize
) -> Option<Selection>

pub fn is_empty(&self) -> bool

pub fn intersects_range<R: RangeBounds<usize>>(&self, range: R) -> bool

Trait Implementations

impl Clone for Selection

fn clone(&self) -> Selection

Returns a copy of the value.

fn clone_from(&mut self, source: &Self)

Performs copy-assignment from source.

impl Debug for Selection

fn fmt(&self, f: &mut Formatter) -> Result

Formats the value using the given formatter.

impl PartialEq<Selection> for Selection

fn eq(&self, other: &Selection) -> bool

This method tests for self and other values to be equal, and is used by ==.

fn ne(&self, other: &Selection) -> bool

This method tests for !=.
