}

A laid out and styled line of text

Fields

font_size: Pixels

The font size for this line

width: Pixels

The width of the line

ascent: Pixels

The ascent of the line

descent: Pixels

The descent of the line

runs: Vec<ShapedRun>

The shaped runs that make up this line

len: usize

Implementations

impl LineLayout

pub fn index_for_x(&self, x: Pixels) -> Option<usize>

The index for the character at the given x coordinate

pub fn closest_index_for_x(&self, x: Pixels) -> usize

closest_index_for_x returns the character boundary closest to the given x coordinate (e.g. to handle aligning up/down arrow keys)

pub fn x_for_index(&self, index: usize) -> Pixels

The x position of the character at the given index

pub fn font_id_for_index(&self, index: usize) -> Option<FontId>

The corresponding Font at the given index

Trait Implementations

impl Debug for LineLayout

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

Formats the value using the given formatter.

impl Default for LineLayout

fn default() -> LineLayout

Returns the “default value” for a type.
