Implementations

impl ScaleFactor

fn one() -> Self

Trait Implementations

impl Clone for ScaleFactor

fn clone(&self) -> ScaleFactor

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for ScaleFactor

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

Formats the value using the given formatter.

impl MallocSizeOf for ScaleFactor

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 Parse for ScaleFactor

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

Scale accepts | , so we parse it as NumberOrPercentage, and then convert into an Number if it’s a non-calc Percentage. https://github.com/w3c/csswg-drafts/pull/4396

impl PartialEq for ScaleFactor

fn eq(&self, other: &ScaleFactor) -> 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 SpecifiedValueInfo for ScaleFactor

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 ToComputedValue for ScaleFactor

type ComputedValue = <Number as ToComputedValue>::ComputedValue

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

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.

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

Convert a computed value to specified value form.

impl ToCss for ScaleFactor

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.

fn to_css_cssstring(&self) -> String

Serialize self in CSS syntax and return a CssString.

impl ToFloat for ScaleFactor

fn to_f32(&self) -> Result<f32, ()>

Return the number as an f32, or Err(()) if the conversion is not possible.

fn to_f64(&self) -> Result<f64, ()>

Return the number as an f64, or Err(()) if the conversion is not possible.

impl ToShmem for ScaleFactor

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

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

impl ToTyped for ScaleFactor

where NumberOrPercentage: ToTyped,

fn to_typed(&self, dest: &mut ThinVec<TypedValue>) -> Result<(), ()>

Attempt to convert self into one or more TypedValue items.

fn to_typed_value(&self) -> Option<TypedValue>

Attempt to convert self into a TypedValue.

fn to_numeric_value(&self) -> Option<NumericValue>

Attempt to convert self into a NumericValue.

fn to_typed_value_list(&self) -> Option<TypedValueList>

Attempt to convert self into a TypedValueList.
