Enum FontStyle 

pub enum FontStyle {
    Normal,
    Italic,
    Oblique(Option<f32>),
}

Visual style or ‘slope’ of a font.

The default value is FontStyle::Normal.

In variable fonts, this can be controlled with the ital and slnt axes for italic and oblique styles, respectively. This uses an f32 for the Oblique variant so so that it can represent the same range of values as the slnt axis.

See https://fonts.google.com/knowledge/glossary/style

In CSS, this corresponds to the font-style property.

Variants

Normal

An upright or “roman” style.

Italic

Generally a slanted style, originally based on semi-cursive forms. This often has a different structure from the normal style.

Oblique(Option<f32>)

Oblique (or slanted) style with an optional angle in degrees, counter-clockwise from the vertical.

Implementations

impl FontStyle

pub fn parse(s: &str) -> Option<FontStyle>

Parses a font style from a CSS value.

impl FontStyle

pub fn from_fontconfig(slant: i32) -> FontStyle

Creates a new style attribute with the given value from Fontconfig.

The values are determined based on the fonts.conf documentation.

Trait Implementations

impl Clone for FontStyle

fn clone(&self) -> FontStyle

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for FontStyle

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

Formats the value using the given formatter.

impl Default for FontStyle

fn default() -> FontStyle

Returns the “default value” for a type.

impl Display for FontStyle

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

Formats the value using the given formatter.

impl PartialEq for FontStyle

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