Struct epaint::text::Row[−][src]

pub struct Row {
    pub x_offsets: Vec<f32>,
    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

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[src]

pub fn sanity_check(&self)[src]

pub fn char_count_excluding_newline(&self) -> usize[src]

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

pub fn char_count_including_newline(&self) -> usize[src]

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

pub fn min_x(&self) -> f32[src]

pub fn max_x(&self) -> f32[src]

pub fn height(&self) -> f32[src]

pub fn rect(&self) -> Rect[src]

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

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[src]
