Enum LineHeightValue 

pub enum LineHeightValue {
    Normal(f32),
    Pt(f32),
}

Specifies how line height is computed for text layout.

Example

use floem_renderer::text::{Attrs, LineHeightValue};

// 1.5x the font size (e.g. 24px for a 16px font).
let attrs = Attrs::new().line_height(LineHeightValue::Normal(1.5));

// Fixed 20-point line height regardless of font size.
let attrs = Attrs::new().line_height(LineHeightValue::Pt(20.0));

Variants

Normal(f32)

A multiplier of the font size (e.g. 1.0 means line height equals font size).

Pt(f32)

An absolute line height in points.

Implementations

impl LineHeightValue

pub fn resolve(&self, font_size: f32) -> f32

Trait Implementations

impl Clone for LineHeightValue

fn clone(&self) -> LineHeightValue

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for LineHeightValue

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

Formats the value using the given formatter.

impl From<f32> for LineHeightValue

fn from(value: f32) -> Self

Converts to this type from the input type.

impl From<f64> for LineHeightValue

fn from(value: f64) -> Self

Converts to this type from the input type.

impl From<i32> for LineHeightValue

fn from(value: i32) -> Self

Converts to this type from the input type.

impl PartialEq for LineHeightValue

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