Struct style::values::computed::font::FontSize
[−]
[src]
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
[src]
pub fn size(self) -> Au
[src]
The actual computed font size.
pub fn medium() -> Self
[src]
Get default value of font size.
pub fn cascade_inherit_font_size(context: &mut Context)
[src]
FIXME(emilio): This is very complex. Also, it should move to StyleBuilder.
pub fn cascade_initial_font_size(context: &mut Context)
[src]
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
[src]
fn animate(&self, other: &Self, procedure: Procedure) -> Result<Self, ()>
[src]
Animate a value towards another one, given an animation procedure.
impl ComputeSquaredDistance for FontSize
[src]
fn compute_squared_distance(&self, other: &Self) -> Result<SquaredDistance, ()>
[src]
Computes the squared distance between two animatable values.
impl MallocSizeOf for FontSize
[src]
fn size_of(&self, ops: &mut MallocSizeOfOps) -> usize
[src]
Measure the heap usage of all descendant heap-allocated structures, but not the space taken up by the value itself. Read more
impl ToAnimatedZero for FontSize
[src]
fn to_animated_zero(&self) -> Result<Self, ()>
[src]
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. Read more
impl Clone for FontSize
[src]
fn clone(&self) -> FontSize
[src]
Returns a copy of the value. Read more
fn clone_from(&mut self, source: &Self)
1.0.0[src]
Performs copy-assignment from source
. Read more
impl Copy for FontSize
[src]
impl Debug for FontSize
[src]
fn fmt(&self, __arg_0: &mut Formatter) -> Result
[src]
Formats the value using the given formatter. Read more
impl PartialEq for FontSize
[src]
fn eq(&self, __arg_0: &FontSize) -> bool
[src]
This method tests for self
and other
values to be equal, and is used by ==
. Read more
fn ne(&self, __arg_0: &FontSize) -> bool
[src]
This method tests for !=
.
impl ToCss for FontSize
[src]
fn to_css<W>(&self, dest: &mut W) -> Result where
W: Write,
[src]
W: Write,
Serialize self
in CSS syntax, writing to dest
.
fn to_css_string(&self) -> String
[src]
Serialize self
in CSS syntax and return a string. Read more
impl ToAnimatedValue for FontSize
[src]
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
[src]
Converts this value to an animated value.
fn from_animated_value(animated: Self::AnimatedValue) -> Self
[src]
Converts back an animated value into a computed value.
