Struct LaidOutLine

pub struct LaidOutLine {
    pub text_range: Range<usize>,
    pub width: f32,
    pub ascent: f32,
    pub descent: f32,
    pub baseline_y: f32,
}

Metrics for one laid-out line.

Distances are logical pixels. text_range is a half-open UTF-8 byte range in the original string. descent follows Parley’s metric convention and is normally non-negative.

Examples

use ailloli_ui_text::LaidOutLine;
let line = LaidOutLine {
    text_range: 0..5,
    width: 40.0,
    ascent: 12.0,
    descent: 4.0,
    baseline_y: 12.0,
};
assert_eq!(line.text_range, 0..5);

Fields

text_range: Range<usize>

Half-open UTF-8 byte range covered by the line.

width: f32

Advance excluding trailing whitespace, in logical pixels.

ascent: f32

Distance above the baseline, in logical pixels.

descent: f32

Distance below the baseline, in logical pixels.

baseline_y: f32

Baseline Y coordinate relative to the layout origin, in logical pixels.

Trait Implementations

impl Clone for LaidOutLine

fn clone(&self) -> LaidOutLine

Returns a copy of the value.

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

Performs copy-assignment from source.

impl Debug for LaidOutLine

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

Formats the value using the given formatter.

impl PartialEq for LaidOutLine

fn eq(&self, other: &LaidOutLine) -> 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.
