Enum PropertyId

pub enum PropertyId {
    NonCustom(NonCustomPropertyId),
    Custom(Name),
}

Representation of a CSS property, that is, either a longhand, a shorthand, or a custom property.

Variants

NonCustom(NonCustomPropertyId)

An alias for a shorthand property.

Custom(Name)

A custom property.

Implementations

impl PropertyId

pub(super) fn parse_unchecked( property_name: &str, use_counters: Option<&UseCounters>, ) -> Result<Self, ()>

Returns a given property from the given name, regardless of whether it is enabled or not, or Err(()) for unknown properties.

impl PropertyId

pub fn longhand_id(&self) -> Option<LonghandId>

Return the longhand id that this property id represents.

pub fn is_animatable(&self) -> bool

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

pub fn parse_unchecked_for_testing(name: &str) -> Result<Self, ()>

Returns a given property from the given name, regardless of whether it is enabled or not, or Err(()) for unknown properties.

Do not use for non-testing purposes.

pub fn parse_enabled_for_all_content(name: &str) -> Result<Self, ()>

Parses a property name, and returns an error if it’s unknown or isn’t enabled for all content.

pub fn parse(name: &str, context: &ParserContext<'_>) -> Result<Self, ()>

Parses a property name, and returns an error if it’s unknown or isn’t allowed in this context.

pub fn parse_ignoring_rule_type( name: &str, context: &ParserContext<'_>, ) -> Result<Self, ()>

Parses a property name, and returns an error if it’s unknown or isn’t allowed in this context, ignoring the rule_type checks.

This is useful for parsing stuff from CSS values, for example.

pub fn is_shorthand(&self) -> bool

Returns true if the property is a shorthand or shorthand alias.

pub fn as_shorthand(&self) -> Result<ShorthandId, PropertyDeclarationId<'_>>

Given this property id, get it either as a shorthand or as a PropertyDeclarationId.

pub fn non_custom_id(&self) -> Option<NonCustomPropertyId>

Returns the NonCustomPropertyId corresponding to this property id.

fn non_custom_non_alias_id(&self) -> Option<NonCustomPropertyId>

Returns non-alias NonCustomPropertyId corresponding to this property id.

pub fn enabled_for_all_content(&self) -> bool

Whether the property is enabled for all content regardless of the stylesheet it was declared on (that is, in practice only checks prefs).

fn allowed_in(&self, context: &ParserContext<'_>) -> bool

fn allowed_in_ignoring_rule_type(&self, context: &ParserContext<'_>) -> bool

pub fn supports_type(&self, ty: u8) -> bool

Whether the property supports the given CSS type. ty should a bitflags of constants in style_traits::CssType.

pub fn collect_property_completion_keywords(&self, f: KeywordsCollectFn<'_>)

Collect supported starting word of values of this property.

See style_traits::SpecifiedValueInfo::collect_completion_keywords for more details.

Trait Implementations

impl Clone for PropertyId

fn clone(&self) -> PropertyId

Returns a copy of the value.

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

Performs copy-assignment from source.

impl Debug for PropertyId

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

Formats the value using the given formatter.

impl PartialEq for PropertyId

fn eq(&self, other: &PropertyId) -> 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 ToCss for PropertyId

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.
