Enum style::values::generics::length::GenericLengthOrNumber

#[repr(C, u8)]
pub enum GenericLengthOrNumber<L, N> {
    Number(N),
    Length(L),
}

A generic <length> | <number> value for the tab-size property.

Variants

Number(N)

A number.

NOTE: Numbers need to be before lengths, in order to parse them first, since 0 should be a number, not the 0px length.

Length(L)

A length.

Trait Implementations

impl<L, N> Animate for GenericLengthOrNumber<L, N>

where L: Animate, N: Animate,

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

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

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

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

Returns a copy of the value.

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

Performs copy-assignment from source.

impl<L, N> ComputeSquaredDistance for GenericLengthOrNumber<L, N>

where L: ComputeSquaredDistance, N: ComputeSquaredDistance,

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

Computes the squared distance between two animatable values.

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

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

Formats the value using the given formatter.

impl<L, N> MallocSizeOf for GenericLengthOrNumber<L, N>

where L: MallocSizeOf, N: 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<L, N> Parse for GenericLengthOrNumber<L, N>

where L: Parse, N: Parse,

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

Parse a value of this type.

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

fn eq(&self, other: &GenericLengthOrNumber<L, N>) -> 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<L, N> SpecifiedValueInfo for GenericLengthOrNumber<L, N>

where L: SpecifiedValueInfo, N: 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<L, N> ToAnimatedValue for GenericLengthOrNumber<L, N>

where L: ToAnimatedValue, N: ToAnimatedValue,

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

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<L, N> ToAnimatedZero for GenericLengthOrNumber<L, N>

where L: ToAnimatedZero, N: ToAnimatedZero,

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<L, N> ToComputedValue for GenericLengthOrNumber<L, N>

where L: ToComputedValue, N: ToComputedValue,

type ComputedValue = GenericLengthOrNumber<<L as ToComputedValue>::ComputedValue, <N as ToComputedValue>::ComputedValue>

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<L, N> ToCss for GenericLengthOrNumber<L, N>

where L: ToCss, N: ToCss,

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<L, N> ToResolvedValue for GenericLengthOrNumber<L, N>

where L: ToResolvedValue, N: ToResolvedValue,

type ResolvedValue = GenericLengthOrNumber<<L as ToResolvedValue>::ResolvedValue, <N as ToResolvedValue>::ResolvedValue>

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.

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

impl<L, N: Zero> Zero for LengthOrNumber<L, N>

fn zero() -> Self

Returns the zero value.
