Struct FontSpec 

Source 
pub struct FontSpec {
    pub family: String,
    pub size: f32,
    pub weight: u16,
    pub style: FontStyle,
    pub letter_spacing: f32,
    pub line_height: Option<f32>,
    pub features: Vec<FontFeature>,
}
Expand description

Font specification for UI text.

The three legacy fields (family, size, weight) plus the FontSpec::new constructor are unchanged. The richer typographic fields (style, letter_spacing, line_height, features) are additive and default to “no override”, so existing call sites are unaffected.

Fields§

§family: String

Font family name.

§size: f32

Font size in points.

§weight: u16

Font weight (100 thin … 900 black; 400 is regular).

§style: FontStyle

Slant style (normal / italic / oblique).

§letter_spacing: f32

Additional inter-character spacing in points (0.0 = font default).

§line_height: Option<f32>

Line height (leading) in points. None uses the font’s natural metrics.

§features: Vec<FontFeature>

OpenType feature toggles applied to runs using this spec.

Implementations§

Source§

impl FontSpec

Source

pub fn new(family: impl Into<String>, size: f32, weight: u16) -> FontSpec

Source

pub fn with_style(self, style: FontStyle) -> FontSpec

Builder: set the slant FontStyle.

Source

pub fn with_letter_spacing(self, letter_spacing: f32) -> FontSpec

Builder: set additional letter spacing in points.

Source

pub fn with_line_height(self, line_height: f32) -> FontSpec

Builder: set the line height (leading) in points.

Source

pub fn with_feature(self, feature: FontFeature) -> FontSpec

Builder: append an OpenType FontFeature.

Source

pub fn is_slanted(&self) -> bool

Returns true if the face is italic or oblique.
