Struct swash::Attributes

pub struct Attributes(pub u32);

Primary attributes for font classification: stretch, weight and style.

This struct is created by the attributes method on FontRef.

Implementations

impl Attributes

pub const fn new(stretch: Stretch, weight: Weight, style: Style) -> Self

Creates new font attributes from the specified stretch, weight and style.

pub fn from_font<'a>(font: &FontRef<'a>) -> Self

Extracts the attributes from the specified font.

pub fn stretch(&self) -> Stretch

Returns the stretch attribute.

pub fn weight(&self) -> Weight

Returns the weight attribute.

pub fn style(&self) -> Style

Returns the style attribute.

pub fn parts(&self) -> (Stretch, Weight, Style)

Returns a tuple containing all attributes.

pub fn has_variations(&self) -> bool

Returns true if the font has variations corresponding to primary attributes.

pub fn has_stretch_variation(&self) -> bool

Returns true if the font has a variation for the stretch attribute.

pub fn has_weight_variation(&self) -> bool

Returns true if the font has a variation for the weight attribute.

pub fn has_oblique_variation(&self) -> bool

Returns true if the font has a variation for the oblique style attribute.

pub fn has_italic_variation(&self) -> bool

Returns true if the font has a variation for the italic style attribute.

pub fn synthesize(&self, requested: Attributes) -> Synthesis

Returns a synthesis analysis based on the requested attributes with respect to this set of attributes.
