Struct epaint::text::Row

pub struct Row {
    pub x_offsets: Vec<f32>,
    pub uv_rects: Vec<Option<UvRect>>,
    pub y_min: f32,
    pub y_max: f32,
    pub ends_with_newline: bool,
}

A typeset piece of text on a single row.

Fields

x_offsets: Vec<f32>

The start of each character, probably starting at zero. The last element is the end of the last character. This is never empty. Unit: points.

x_offsets.len() + (ends_with_newline as usize) == text.chars().count() + 1

uv_rects: Vec<Option<UvRect>>

Per-character. Used when rendering.

y_min: f32

Top of the row, offset within the Galley. Unit: points.

y_max: f32

Bottom of the row, offset within the Galley. Unit: points.

ends_with_newline: bool

If true, this Row came from a paragraph ending with a \n. The \n itself is omitted from x_offsets. 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 sanity_check(&self)

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 min_x(&self) -> f32

pub fn max_x(&self) -> f32

pub fn height(&self) -> f32

pub fn rect(&self) -> Rect

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

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

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

pub fn translate_y(&mut self, dy: f32)

Trait Implementations

impl Clone for Row

fn clone(&self) -> Row

Returns a copy 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<Row> for Row

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

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

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

This method tests for !=.
