Implementations

impl<N, L> LineHeight<N, L>

pub fn normal() -> Self

Returns normal.

Trait Implementations

impl<N, L> Animate for GenericLineHeight<N, L>where N: Animate, L: Animate,

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

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

impl<N: Clone, L: Clone> Clone for GenericLineHeight<N, L>

fn clone(&self) -> GenericLineHeight<N, L>

Returns a copy of the value.

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

Performs copy-assignment from source.

impl<N, L> ComputeSquaredDistance for GenericLineHeight<N, L>where N: ComputeSquaredDistance, L: ComputeSquaredDistance,

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

Computes the squared distance between two animatable values.

impl<N: Debug, L: Debug> Debug for GenericLineHeight<N, L>

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

Formats the value using the given formatter.

impl<'de, N, L> Deserialize<'de> for GenericLineHeight<N, L>where N: Deserialize<'de>, L: Deserialize<'de>,

fn deserialize<__D>(__deserializer: __D) -> Result<Self, __D::Error>where __D: Deserializer<'de>,

Deserialize this value from the given Serde deserializer.

impl<N, L> MallocSizeOf for GenericLineHeight<N, L>where N: MallocSizeOf, L: MallocSizeOf,

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<N, L> Parse for GenericLineHeight<N, L>where N: Parse, L: Parse,

fn parse<'i, 't>( context: &ParserContext<'_>, input: &mut Parser<'i, 't> ) -> Result<Self, ParseError<'i>>

Parse a value of this type.

impl<N: PartialEq, L: PartialEq> PartialEq<GenericLineHeight<N, L>> for GenericLineHeight<N, L>

fn eq(&self, other: &GenericLineHeight<N, L>) -> 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<N, L> Serialize for GenericLineHeight<N, L>where N: Serialize, L: Serialize,

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

Serialize this value into the given Serde serializer.

impl<N, L> SpecifiedValueInfo for GenericLineHeight<N, L>where N: SpecifiedValueInfo, L: SpecifiedValueInfo,

const SUPPORTED_TYPES: u8 = _

Supported CssTypes by the given value type.

fn collect_completion_keywords(_f: &mut dyn FnMut(&[&'static str]))

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.

impl<N, L> ToAnimatedValue for GenericLineHeight<N, L>where N: ToAnimatedValue, L: ToAnimatedValue,

type AnimatedValue = GenericLineHeight<<N as ToAnimatedValue>::AnimatedValue, <L as ToAnimatedValue>::AnimatedValue>

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

Converts back an animated value into a computed value.

fn to_animated_value(self) -> Self::AnimatedValue

Converts this value to an animated value.

impl<N, L> ToAnimatedZero for LineHeight<N, L>

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 LineHeight

type ComputedValue = GenericLineHeight<NonNegative<f32>, NonNegative<CSSPixelLength>>

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