Struct Row 

pub struct Row {
    pub(crate) section_index_at_start: u32,
    pub glyphs: Vec<Glyph>,
    pub size: Vec2,
    pub visuals: RowVisuals,
    pub ends_with_newline: bool,
}

Fields

section_index_at_start: u32

This is included in case there are no glyphs.

Only used during layout, then set to an invalid value in order to enable the paragraph-concat optimization path without having to adjust section_index when concatting.

glyphs: Vec<Glyph>

One for each char.

size: Vec2

Logical size based on font heights etc. Includes leading and trailing whitespace.

visuals: RowVisuals

The mesh, ready to be rendered.

ends_with_newline: bool

If true, this Row came from a paragraph ending with a \n. The \n itself is omitted from Self::glyphs. A \n in the input text always creates a new Row below it, so that text that ends with \n has an empty Row last. This also implies that the last Row in a Galley always has ends_with_newline == false.

Implementations

impl Row

pub fn text(&self) -> String

The text on this row, excluding the implicit \n if any.

pub fn char_count_excluding_newline(&self) -> usize

Excludes the implicit \n after the Row, if any.

pub fn char_count_including_newline(&self) -> usize

Includes the implicit \n after the Row, if any.

pub fn char_at(&self, desired_x: f32) -> usize

Closest char at the desired x coordinate in row-relative coordinates. Returns something in the range [0, char_count_excluding_newline()].

pub fn x_offset(&self, column: usize) -> f32

pub fn height(&self) -> f32

Trait Implementations

impl Clone for Row

fn clone(&self) -> Row

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for Row

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

Formats the value using the given formatter.

impl PartialEq for Row

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

Tests for self and other values to be equal, and is used by ==.

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

Tests for !=. The default implementation is almost always sufficient, and should not be overridden without very good reason.
