Implementations§

source§

impl PropertyId

source

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.

source§

impl PropertyId

source

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

Return the longhand id that this property id represents.

source

pub fn is_animatable(&self) -> bool

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

source

pub fn is_transitionable(&self) -> bool

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

source

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.

source

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.

source

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.

source

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.

source

pub fn is_shorthand(&self) -> bool

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

source

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

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

source

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

Returns the NonCustomPropertyId corresponding to this property id.

source

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

Returns non-alias NonCustomPropertyId corresponding to this property id.

source

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).

source

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

source

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

source

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.

source

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.
