Struct style::values::computed::font::FontSize

pub struct FontSize {
    pub computed_size: NonNegativeLength,
    pub used_size: NonNegativeLength,
    pub keyword_info: KeywordInfo,
}

The computed value of font-size

Fields

computed_size: NonNegativeLength

The computed size, that we use to compute ems etc. This accounts for e.g., text-zoom.

used_size: NonNegativeLength

The actual used size. This is the computed font size, potentially constrained by other factors like minimum font-size settings and so on.

keyword_info: KeywordInfo

If derived from a keyword, the keyword and additional transformations applied to it

Implementations

impl FontSize

pub fn computed_size(&self) -> Length

The actual computed font size.

pub fn used_size(&self) -> Length

The actual used font size.

pub fn zoom(&self, zoom: Zoom) -> Self

Apply zoom to the font-size. This is usually done by ToComputedValue.

pub fn medium() -> Self

Get default value of font size.

Trait Implementations

impl Animate for FontSize

fn animate(&self, other: &Self, procedure: Procedure) -> Result<Self, ()>

Animate a value towards another one, given an animation procedure.

impl Clone for FontSize

fn clone(&self) -> FontSize

Returns a copy of the value.

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

Performs copy-assignment from source.

impl ComputeSquaredDistance for FontSize

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

Computes the squared distance between two animatable values.

impl Debug for FontSize

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

Formats the value using the given formatter.

impl<'de> Deserialize<'de> for FontSize

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

where __D: Deserializer<'de>,

Deserialize this value from the given Serde deserializer.

impl MallocSizeOf for FontSize

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 FontSize

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

impl Serialize for FontSize

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 FontSize

type AnimatedValue = CSSPixelLength

The type of the animated value.

fn to_animated_value(self, context: &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.

impl ToAnimatedZero for FontSize

fn to_animated_zero(&self) -> Result<Self, ()>

Returns a value that, when added with an underlying value, will produce the underlying value. This is used for SMIL animation’s “by-animation” where SMIL first interpolates from the zero value to the ‘by’ value, and then adds the result to the underlying value.

impl ToCss for FontSize

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 FontSize

type ResolvedValue = NonNegative<CSSPixelLength>

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

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

Convert a resolved value to a resolved value.

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

Convert a resolved value to resolved value form.

impl Copy for FontSize

impl StructuralPartialEq for FontSize
