Struct ParagraphMetrics

pub struct ParagraphMetrics {
    pub width: f32,
    pub height: f32,
    pub line_count: usize,
    pub local_version: u64,
}

Cached metrics for one logical paragraph under one layout configuration.

Width and height are logical pixels, line_count counts shaped visual lines, and local_version mirrors the source paragraph revision.

Examples

use ailloli_ui_editor::layout::ParagraphMetrics;
let metrics = ParagraphMetrics { width: 80.0, height: 36.0, line_count: 2, local_version: 7 };
assert_eq!(metrics.line_count, 2);

Fields

width: f32

Maximum shaped line width in logical pixels.

height: f32

Complete paragraph visual height in logical pixels.

line_count: usize

Number of shaped visual lines, normally at least one.

local_version: u64

Source paragraph revision from which these metrics were computed.

Trait Implementations

impl Clone for ParagraphMetrics

fn clone(&self) -> ParagraphMetrics

Returns a copy of the value.

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

Performs copy-assignment from source.

impl Debug for ParagraphMetrics

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

Formats the value using the given formatter.

impl PartialEq for ParagraphMetrics

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