Methods

impl LengthOrPercentage

pub fn zero() -> LengthOrPercentage

Returns a zero length.

pub fn parse_non_negative<'i, 't>(
    context: &ParserContext,
    input: &mut Parser<'i, 't>
) -> Result<LengthOrPercentage, ParseError<'i>>

Parse a non-negative length.

pub fn parse_non_negative_quirky<'i, 't>(
    context: &ParserContext,
    input: &mut Parser<'i, 't>,
    allow_quirks: AllowQuirks
) -> Result<LengthOrPercentage, ParseError<'i>>

Parse a non-negative length, with quirks.

pub fn parse_numbers_are_pixels<'i, 't>(
    context: &ParserContext,
    input: &mut Parser<'i, 't>
) -> Result<LengthOrPercentage, ParseError<'i>>

Parse a length, treating dimensionless numbers as pixels

pub fn parse_numbers_are_pixels_non_negative<'i, 't>(
    context: &ParserContext,
    input: &mut Parser<'i, 't>
) -> Result<LengthOrPercentage, ParseError<'i>>

Parse a non-negative length, treating dimensionless numbers as pixels

This is nonstandard behavior used by Firefox for SVG

pub fn take(&mut self) -> Self

Extract value from ref without a clone, replacing it with a 0 Au

Use when you need to move out of a length array without cloning

impl LengthOrPercentage

pub fn parse_quirky<'i, 't>(
    context: &ParserContext,
    input: &mut Parser<'i, 't>,
    allow_quirks: AllowQuirks
) -> Result<Self, ParseError<'i>>

Parses a length or a percentage, allowing the unitless length quirk. https://quirks.spec.whatwg.org/#the-unitless-length-quirk

Trait Implementations

impl ToComputedValue for LengthOrPercentage

type ComputedValue = LengthOrPercentage

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

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

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

fn from_computed_value(computed: &LengthOrPercentage) -> Self

Convert a computed value to specified value form.

impl ToAbsoluteLength for SpecifiedLengthOrPercentage

fn to_pixel_length(&self, _containing_len: Option<Au>) -> Result<CSSFloat, ()>

Returns the absolute length as pixel value.

impl From<LengthOrPercentage> for FontSize

fn from(other: LengthOrPercentage) -> Self

Performs the conversion.

impl Clone for LengthOrPercentage

fn clone(&self) -> LengthOrPercentage

Returns a copy of the value.

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