Enum style::values::specified::length::Length

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

An extension to NoCalcLength to parse calc expressions. This is commonly used for the <length> values.

Variants

NoCalc(NoCalcLength)

The internal length type that cannot parse calc

Calc(Box<CalcLengthPercentage>)

A calc expression.

Implementations

impl Length

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

Parse a non-negative length, allowing quirks.

pub fn from_px(px_value: CSSFloat) -> Length

Get an absolute length from a px value.

pub fn to_computed_pixel_length_without_context(&self) -> Result<CSSFloat, ()>

Get a px value without context.

impl Length

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

Parses a length, with quirks.

Trait Implementations

impl Clone for Length

fn clone(&self) -> Length

Returns a copy of the value.

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

Performs copy-assignment from source.

impl Debug for Length

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<Length> for NonNegativeLength

fn from(len: Length) -> Self

Converts to this type from the input type.

impl From<NoCalcLength> for Length

fn from(len: NoCalcLength) -> Self

Converts to this type from the input type.

impl MallocSizeOf for Length

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 Length

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

Parse a value of this type.

impl PartialEq for Length

fn eq(&self, other: &Length) -> 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 Length

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 Length

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

Returns the absolute length as pixel value.

impl ToComputedValue for Length

type ComputedValue = CSSPixelLength

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 Length

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 Length

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

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

impl Zero for Length

fn zero() -> Self

Returns the zero value.

fn is_zero(&self) -> bool

Returns whether this value is zero.

impl StructuralPartialEq for Length
