Struct TextStyle

pub struct TextStyle {
    pub family: FontRef,
    pub weight: u16,
    pub style: FontStyle,
    pub size: f32,
    pub line_height: LineHeight,
    pub letter_spacing: f32,
    pub transform: TextTransform,
    pub decoration: TextDecoration,
    pub color: Option<String>,
}

A resolved text style: family, weight, size, line-height and the visual modifiers that go with them.

color is a slot id (string) rather than a resolved crate::types::Color because the slot store is what knows how to resolve names to values — and widgets can override the colour with [.color()] at the call-site, which always wins over the style’s default.

Fields

family: FontRef

Font family, looked up in the theme’s fonts block.

weight: u16

Weight as a CSS numeric value (100..=900).

style: FontStyle

Italic vs upright.

size: f32

Font size in CSS pixels.

line_height: LineHeight

Line height.

letter_spacing: f32

Letter spacing in em (fraction of the font size). 0.0 by default.

transform: TextTransform

Case transform applied before shaping.

decoration: TextDecoration

Underline / strikethrough.

color: Option<String>

Default colour slot id. None means “inherit from the widget’s own colour setting”. When Some, widgets that don’t override with [.color()] get this.

Implementations

impl TextStyle

pub fn new( family: FontRef, weight: u16, size: f32, line_height: LineHeight, ) -> Self

Convenience constructor that fills the non-essential fields with sensible defaults (upright, no transform, no decoration, no default colour, no letter spacing).

Trait Implementations

impl Clone for TextStyle

fn clone(&self) -> TextStyle

Returns a copy of the value.

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

Performs copy-assignment from source.

impl Debug for TextStyle

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

Formats the value using the given formatter.

impl PartialEq for TextStyle

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