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.

Tuple Fields

0: u32

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.

Trait Implementations

impl Clone for Attributes

fn clone(&self) -> Attributes

Returns a copy of the value.

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

Performs copy-assignment from source.

impl Debug for Attributes

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

Formats the value using the given formatter.

impl Default for Attributes

fn default() -> Self

Returns the “default value” for a type.

impl Display for Attributes

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

Formats the value using the given formatter.

impl From<()> for Attributes

fn from(_: ()) -> Self

Converts to this type from the input type.

impl From<(Stretch, Weight, Style)> for Attributes

fn from(parts: (Stretch, Weight, Style)) -> Self

Converts to this type from the input type.

impl From<Stretch> for Attributes

fn from(s: Stretch) -> Self

Converts to this type from the input type.

impl From<Style> for Attributes

fn from(s: Style) -> Self

Converts to this type from the input type.

impl From<Weight> for Attributes

fn from(w: Weight) -> Self

Converts to this type from the input type.

impl Hash for Attributes

fn hash<H: Hasher>(&self, state: &mut H)

Feeds this value into the given Hasher.

fn hash_slice<H>(data: &[Self], state: &mut H)

where H: Hasher, Self: Sized,

Feeds a slice of this type into the given Hasher.

impl PartialEq for Attributes

fn eq(&self, other: &Self) -> bool

This method tests for self and other values to be equal, and is used by ==.

fn ne(&self, other: &Rhs) -> bool

This method tests for !=. The default implementation is almost always sufficient, and should not be overridden without very good reason.
