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

pub struct FontSize {
    pub size: NonNegativeLength,
    pub keyword_info: Option<KeywordInfo>,
}

The computed value of font-size

Fields

size: NonNegativeLength

The size.

keyword_info: Option<KeywordInfo>

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

Methods

impl FontSize

pub fn size(self) -> Au

The actual computed font size.

pub fn medium() -> Self

Get default value of font size.

pub fn cascade_inherit_font_size(context: &mut Context)

FIXME(emilio): This is very complex. Also, it should move to StyleBuilder.

pub fn cascade_initial_font_size(context: &mut Context)

Cascade the initial value for the font-size property.

FIXME(emilio): This is the only function that is outside of the StyleBuilder, and should really move inside!

Can we move the font stuff there?

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 ComputeSquaredDistance for FontSize

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

Computes the squared distance between two animatable values.

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 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 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 Copy for FontSize

impl Debug for FontSize

fn fmt(&self, __arg_0: &mut Formatter) -> Result

Formats the value using the given formatter.

impl PartialEq for FontSize

fn eq(&self, __arg_0: &FontSize) -> bool

This method tests for self and other values to be equal, and is used by ==.

fn ne(&self, __arg_0: &FontSize) -> bool

This method tests for !=.

impl ToCss for FontSize

fn to_css<W>(&self, dest: &mut 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 ToAnimatedValue for FontSize

XXXManishearth it might be better to animate this as computed, however this complicates clamping and might not be the right thing to do. We should figure it out.

type AnimatedValue = NonNegativeLength

The type of the animated value.

fn to_animated_value(self) -> 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.
