Struct style::values::computed::font::KeywordInfo

pub struct KeywordInfo {
    pub kw: KeywordSize,
    pub factor: f32,
    pub offset: NonNegativeLength,
}

Additional information for keyword-derived font sizes.

Fields

kw: KeywordSize

The keyword used

factor: f32

A factor to be multiplied by the computed size of the keyword

offset: NonNegativeLength

An additional Au offset to add to the kw*factor in the case of calcs

Methods

impl KeywordInfo

pub fn to_computed_value(&self, context: &Context) -> NonNegativeLength

Computes the final size for this font-size keyword, accounting for text-zoom.

pub fn compose(self, factor: f32, offset: NonNegativeLength) -> Self

Given a parent keyword info (self), apply an additional factor/offset to it

pub fn medium() -> Self

KeywordInfo value for font-size: medium

Trait Implementations

impl Animate for KeywordInfo

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

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

impl ComputeSquaredDistance for KeywordInfo

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

Computes the squared distance between two animatable values.

impl MallocSizeOf for KeywordInfo

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 ToAnimatedValue for KeywordInfo

type AnimatedValue = KeywordInfo

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.

impl ToAnimatedZero for KeywordInfo

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 KeywordInfo

fn clone(&self) -> KeywordInfo

Returns a copy of the value.

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

Performs copy-assignment from source.

impl Copy for KeywordInfo

impl Debug for KeywordInfo

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

Formats the value using the given formatter.

impl PartialEq for KeywordInfo

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

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

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

This method tests for !=.

impl From<KeywordSize> for KeywordInfo

fn from(x: KeywordSize) -> Self

Performs the conversion.
