Implementations

impl<S: Parse> PositionComponent<S>

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

Parses a component of a CSS position, with quirks.

impl<S> PositionComponent<S>

pub fn zero() -> Self

0%

fn component_count(&self) -> usize

Returns the count of this component.

impl<S: Side> PositionComponent<S>

pub fn initial_specified_value() -> Self

The initial specified value of a position component, i.e. the start side.

Trait Implementations

impl<S: Clone> Clone for PositionComponent<S>

fn clone(&self) -> PositionComponent<S>

Returns a copy of the value.

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

Performs copy-assignment from source.

impl<S: Debug> Debug for PositionComponent<S>

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

Formats the value using the given formatter.

impl<S> MallocSizeOf for PositionComponent<S>

where S: MallocSizeOf,

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<S: Parse> Parse for PositionComponent<S>

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

Parse a value of this type.

impl<S: PartialEq> PartialEq for PositionComponent<S>

fn eq(&self, other: &PositionComponent<S>) -> 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<S> PositionComponent for PositionComponent<S>

fn is_center(&self) -> bool

Returns if the position component is 50% or center. For pixel lengths, it always returns false.

impl<S> SpecifiedValueInfo for PositionComponent<S>

where S: SpecifiedValueInfo,

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<S: Side> ToComputedValue for PositionComponent<S>

type ComputedValue = LengthPercentage

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<S> ToCss for PositionComponent<S>

where S: ToCss,

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<S> ToShmem for PositionComponent<S>

where S: ToShmem,

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

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