Implementations

impl StyleFeature

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

fn matches(&self, ctx: &Context<'_>) -> KleeneValue

Trait Implementations

impl Clone for StyleFeature

fn clone(&self) -> StyleFeature

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for StyleFeature

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

Formats the value using the given formatter.

impl MallocSizeOf for StyleFeature

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 for StyleFeature

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

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 StyleFeature

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

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