Struct style::values::specified::font::KeywordInfo

pub struct KeywordInfo {
    pub kw: FontSizeKeyword,
    pub factor: f32,
    pub offset: CSSPixelLength,
}

Additional information for keyword-derived font sizes.

Fields

kw: FontSizeKeyword

The keyword used

factor: f32

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

offset: CSSPixelLength

An additional fixed offset to add to the kw * factor in the case of calc().

Implementations

impl KeywordInfo

pub fn medium() -> Self

KeywordInfo value for font-size: medium

pub fn none() -> Self

KeywordInfo value for font-size: none

fn new(kw: FontSizeKeyword) -> Self

fn to_computed_value(&self, context: &Context<'_>) -> CSSPixelLength

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

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

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

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 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 ComputeSquaredDistance for KeywordInfo

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

Computes the squared distance between two animatable values.

impl Debug for KeywordInfo

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

Formats the value using the given formatter.

impl<'de> Deserialize<'de> for KeywordInfo

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

where __D: Deserializer<'de>,

Deserialize this value from the given Serde deserializer.

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 PartialEq for KeywordInfo

fn eq(&self, other: &KeywordInfo) -> 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 Serialize for KeywordInfo

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

where __S: Serializer,

Serialize this value into the given Serde serializer.

impl SpecifiedValueInfo for KeywordInfo

fn collect_completion_keywords(f: KeywordsCollectFn<'_>)

Collect value starting words for the given specified value type. This includes keyword and function names which can appear at the beginning of a value of this type.

const SUPPORTED_TYPES: u8 = 0u8

Supported CssTypes by the given value type.

impl ToAnimatedValue for KeywordInfo

where FontSizeKeyword: ToAnimatedValue<AnimatedValue = FontSizeKeyword>, f32: ToAnimatedValue<AnimatedValue = f32>, CSSPixelLength: ToAnimatedValue<AnimatedValue = CSSPixelLength>,

type AnimatedValue = KeywordInfo

The type of the animated value.

fn from_animated_value(from: Self::AnimatedValue) -> Self

Converts back an animated value into a computed value.

fn to_animated_value(self, context: &Context<'_>) -> Self::AnimatedValue

Converts this value to an animated 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 ToComputedValue for KeywordInfo

where FontSizeKeyword: ToComputedValue<ComputedValue = FontSizeKeyword>, f32: ToComputedValue<ComputedValue = f32>, CSSPixelLength: ToComputedValue<ComputedValue = CSSPixelLength>,

type ComputedValue = KeywordInfo

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

fn from_computed_value(from: &Self::ComputedValue) -> Self

Convert a computed value to specified value form.

fn to_computed_value(&self, context: &Context<'_>) -> Self::ComputedValue

Convert a specified value to a computed value, using itself and the data inside the Context.

impl ToCss for KeywordInfo

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 KeywordInfo

where FontSizeKeyword: ToResolvedValue<ResolvedValue = FontSizeKeyword>, f32: ToResolvedValue<ResolvedValue = f32>, CSSPixelLength: ToResolvedValue<ResolvedValue = CSSPixelLength>,

type ResolvedValue = KeywordInfo

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

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

Convert a resolved value to resolved value form.

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

Convert a resolved value to a resolved value.

impl ToShmem for KeywordInfo

fn to_shmem(&self, builder: &mut SharedMemoryBuilder) -> Result<Self>

Clones this value into a form suitable for writing into a SharedMemoryBuilder.

impl Copy for KeywordInfo

impl StructuralPartialEq for KeywordInfo
