WithVariables(VariableDeclaration)

An unparsed declaration.

Custom(CustomDeclaration)

A custom property declaration.

Implementations

impl PropertyDeclaration

pub fn to_css(&self, dest: &mut CssStringWriter) -> Result

Like the method on ToCss, but without the type parameter to avoid accidentally monomorphizing this large function multiple times for different writers.

impl PropertyDeclaration

pub fn id(&self) -> PropertyDeclarationId

Given a property declaration, return the property declaration id.

pub fn to_physical(&self, wm: WritingMode) -> Self

Given a declaration, convert it into a declaration for a corresponding physical property.

fn with_variables_from_shorthand(&self, shorthand: ShorthandId) -> Option<&str>

pub fn css_wide_keyword(id: LonghandId, keyword: CSSWideKeyword) -> Self

Returns a CSS-wide keyword declaration for a given property.

pub fn get_css_wide_keyword(&self) -> Option<CSSWideKeyword>

Returns a CSS-wide keyword if the declaration's value is one.

pub fn get_system(&self) -> Option<SystemFont>

Returns whether or not the property is set by a system font

pub fn is_default_line_height(&self) -> bool

Is it the default value of line-height?

pub fn may_serialize_as_part_of_shorthand(&self) -> bool

Returns whether the declaration may be serialized as part of a shorthand.

This method returns false if this declaration contains variable or has a CSS-wide keyword value, since these values cannot be serialized as part of a shorthand.

Caller should check with_variables_from_shorthand() and whether all needed declarations has the same CSS-wide keyword first.

Note that, serialization of a shorthand may still fail because of other property-specific requirement even when this method returns true for all the longhand declarations.

pub fn value_is_unparsed(&self) -> bool

Return whether the value is stored as it was in the CSS source, preserving whitespace (as opposed to being parsed into a more abstract data structure).

This is the case of custom properties and values that contain unsubstituted variables.

pub fn is_animatable(&self) -> bool

Returns true if this property declaration is for one of the animatable properties.

pub fn is_custom(&self) -> bool

Returns true if this property is a custom property, false otherwise.

pub fn parse_into<'i, 't>(
    declarations: &mut SourcePropertyDeclaration,
    id: PropertyId,
    context: &ParserContext,
    input: &mut Parser<'i, 't>
) -> Result<(), ParseError<'i>>

The context parameter controls this:

https://drafts.csswg.org/css-animations/#keyframes

The inside of accepts any CSS property except those defined in this specification, but does accept the animation-play-state property and interprets it specially.

This will not actually parse Importance values, and will always set things to Importance::Normal. Parsing Importance values is the job of PropertyDeclarationParser, we only set them here so that we don't have to reallocate

Trait Implementations

impl Clone for PropertyDeclaration

fn clone(&self) -> Self

Returns a copy of the value.

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

Performs copy-assignment from source.

impl Debug for PropertyDeclaration

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

Formats the value using the given formatter.

impl MallocSizeOf for PropertyDeclaration

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 PartialEq<PropertyDeclaration> for PropertyDeclaration

fn eq(&self, other: &Self) -> bool

This method tests for self and other values to be equal, and is used by ==.

#[must_use]fn ne(&self, other: &Rhs) -> bool

This method tests for !=.

impl ToShmem for PropertyDeclaration

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

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