Implementations§

source§

impl LengthPercentage

source

pub fn zero_percent() -> LengthPercentage

Returns a 0% value.

source

pub fn hundred_percent() -> LengthPercentage

Returns a 100% value.

source

fn parse_internal<'i, 't>( context: &ParserContext<'_>, input: &mut Parser<'i, 't>, num_context: AllowedNumericType, allow_quirks: AllowQuirks ) -> Result<Self, ParseError<'i>>

source

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

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

source

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

Parse a non-negative length.

FIXME(emilio): This should be not public and we should use NonNegativeLengthPercentage instead.

source

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

source

fn to_calc_node(self) -> CalcNode

Returns self as specified::calc::CalcNode. Note that this expect the clamping_mode is AllowedNumericType::All for Calc. The caller should take care about it when using this function.

source

pub fn hundred_percent_minus(self, clamping_mode: AllowedNumericType) -> Self

Construct the value representing calc(100% - self).
