Enum style::values::specified::length::LengthPercentage

pub enum LengthPercentage {
    Length(NoCalcLength),
    Percentage(Percentage),
    Calc(Box<CalcLengthPercentage>),
}

A <length-percentage> value. This can be either a <length>, a <percentage>, or a combination of both via calc().

Variants

Length(NoCalcLength)

Percentage(Percentage)

Calc(Box<CalcLengthPercentage>)

Implementations

impl LengthPercentage

pub fn zero_percent() -> LengthPercentage

Returns a 0% value.

pub fn hundred_percent() -> LengthPercentage

Returns a 100% value.

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

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

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.

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

Parse a non-negative length, with quirks.

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.

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

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

Trait Implementations

impl Clone for LengthPercentage

fn clone(&self) -> LengthPercentage

Returns a copy of the value.

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

Performs copy-assignment from source.

impl Debug for LengthPercentage

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

Formats the value using the given formatter.

impl From<Length> for LengthPercentage

fn from(len: Length) -> LengthPercentage

Converts to this type from the input type.

impl From<NoCalcLength> for LengthPercentage

fn from(len: NoCalcLength) -> Self

Converts to this type from the input type.

impl From<Percentage> for LengthPercentage

fn from(pc: Percentage) -> Self

Converts to this type from the input type.

impl From<Percentage> for LengthPercentage

fn from(pc: Percentage) -> Self

Converts to this type from the input type.

impl MallocSizeOf for LengthPercentage

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 LengthPercentage

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

Parse a value of this type.

impl PartialEq for LengthPercentage

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

const SUPPORTED_TYPES: u8 = 0u8

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 ToAbsoluteLength for LengthPercentage

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

Returns the absolute length as pixel value.

impl ToComputedValue for LengthPercentage

type ComputedValue = LengthPercentage

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

fn to_computed_value(&self, context: &Context<'_>) -> LengthPercentage

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

fn from_computed_value(computed: &LengthPercentage) -> Self

Convert a computed value to specified value form.

impl ToCss for LengthPercentage

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 ToShmem for LengthPercentage

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

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

impl Zero for LengthPercentage

fn zero() -> Self

Returns the zero value.

fn is_zero(&self) -> bool

Returns whether this value is zero.

impl ZeroNoPercent for LengthPercentage

fn is_zero_no_percent(&self) -> bool

So, 0px should return true, but 0% or 1px should return false

impl StructuralPartialEq for LengthPercentage
