Implementations

impl FontWeight

pub const NORMAL: FontWeight

The normal keyword.

pub const BOLD: FontWeight

The bold value.

pub const BOLD_THRESHOLD: FontWeight

The threshold from which we consider a font bold.

pub const PREFER_BOLD_THRESHOLD: FontWeight

The threshold above which CSS font matching prefers bolder faces over lighter ones.

pub fn normal() -> FontWeight

Returns the normal keyword value.

pub fn is_bold(&self) -> bool

Whether this weight is bold

pub fn value(&self) -> f32

Returns the value as a float.

pub fn from_float(v: f32) -> FontWeight

Trait Implementations

impl Clone for FontWeight

fn clone(&self) -> FontWeight

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl ComputeSquaredDistance for FontWeight

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

Computes the squared distance between two animatable values.

impl Debug for FontWeight

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

Formats the value using the given formatter.

impl<'de> Deserialize<'de> for FontWeight

fn deserialize<__D>( __deserializer: __D, ) -> Result<FontWeight, <__D as Deserializer<'de>>::Error>

where __D: Deserializer<'de>,

Deserialize this value from the given Serde deserializer.

impl Hash for FontWeight

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

where __H: Hasher,

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 FontWeight

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 FontWeight

fn eq(&self, other: &FontWeight) -> 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 FontWeight

fn partial_cmp(&self, other: &FontWeight) -> 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.

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

where __S: Serializer,

Serialize this value into the given Serde serializer.

impl ToAnimatedValue for FontWeight

type AnimatedValue = f32

The type of the animated value.

fn to_animated_value( self, _: &Context<'_>, ) -> <FontWeight as ToAnimatedValue>::AnimatedValue

fn from_animated_value( animated: <FontWeight as ToAnimatedValue>::AnimatedValue, ) -> FontWeight

Converts back an animated value into a computed value.

impl ToCss for FontWeight

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

where W: Write,

Serialize self in CSS syntax, writing to dest.

fn to_css_string(&self) -> String
