Struct style::values::computed::font::FontStyle

#[repr(C)]
pub struct FontStyle(FontStyleFixedPoint);

The computed value of font-style.

• Define out of range values min value (-128.0) as meaning ‘normal’
• Define max value (127.99609375) as ‘italic’
• Other values represent ‘oblique ’
• Note that ‘oblique 0deg’ is distinct from ‘normal’ (should it be?)

Implementations

impl FontStyle

pub const NORMAL: FontStyle = _

The normal keyword.

pub const ITALIC: FontStyle = _

The italic keyword.

pub const DEFAULT_OBLIQUE_DEGREES: i16 = 14i16

The default angle for font-style: oblique. See also https://github.com/w3c/csswg-drafts/issues/2295

pub const OBLIQUE: FontStyle = _

The oblique keyword with the default degrees.

pub fn normal() -> Self

The normal value.

pub fn oblique(degrees: f32) -> Self

Returns the oblique angle for this style.

pub fn oblique_degrees(&self) -> f32

Returns the oblique angle for this style.

Trait Implementations

impl Clone for FontStyle

fn clone(&self) -> FontStyle

Returns a copy of the value.

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

Performs copy-assignment from source.

impl ComputeSquaredDistance for FontStyle

fn compute_squared_distance(&self, other: &Self) -> Result<SquaredDistance, ()>

Computes the squared distance between two animatable values.

impl Debug for FontStyle

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

Formats the value using the given formatter.

impl<'de> Deserialize<'de> for FontStyle

fn deserialize<__D>(__deserializer: __D) -> Result<Self, __D::Error>

where __D: Deserializer<'de>,

Deserialize this value from the given Serde deserializer.

impl Hash for FontStyle

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 MallocSizeOf for FontStyle

fn size_of(&self, ops: &mut MallocSizeOfOps) -> usize

Measure the heap usage of all descendant heap-allocated structures, but not the space taken up by the value itself.

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.

impl PartialOrd for FontStyle

fn partial_cmp(&self, other: &FontStyle) -> Option<Ordering>

This method returns an ordering between self and other values if one exists.

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

Tests less than (for self and other) and is used by the < operator.

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

Tests less than or equal to (for self and other) and is used by the <= operator.

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

Tests greater than (for self and other) and is used by the > operator.

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

Tests greater than or equal to (for self and other) and is used by the >= operator.

impl Serialize for FontStyle

fn serialize<__S>(&self, __serializer: __S) -> Result<__S::Ok, __S::Error>

where __S: Serializer,

Serialize this value into the given Serde serializer.

impl ToAnimatedValue for FontStyle

type AnimatedValue = FontStyle<Angle>

The type of the animated value.

fn to_animated_value(self, _: &Context<'_>) -> Self::AnimatedValue

Converts this value to an animated value.

fn from_animated_value(animated: Self::AnimatedValue) -> Self

Converts back an animated value into a computed value.

fn to_css<W>(&self, dest: &mut CssWriter<'_, W>) -> Result

where W: Write,

Serialize self in CSS syntax, writing to dest.

fn to_css_string(&self) -> String

Serialize self in CSS syntax and return a string.

impl ToResolvedValue for FontStyle

where FontStyleFixedPoint: ToResolvedValue<ResolvedValue = FontStyleFixedPoint>,

type ResolvedValue = FontStyle

The resolved value type we’re going to be converted to.

fn from_resolved_value(from: Self::ResolvedValue) -> Self

Convert a resolved value to resolved value form.

fn to_resolved_value(self, context: &Context<'_>) -> Self::ResolvedValue

Convert a resolved value to a resolved value.
