Struct FontStyle 

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

The computed value of font-style.

• Define angle of zero degrees as normal
• Define out-of-range value 100 degrees as italic
• Other values represent oblique <angle>

Implementations

impl FontStyle

pub const NORMAL: FontStyle

The normal keyword, equal to oblique with angle zero.

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 duplicate 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.

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.
