Struct selectors::parser::SelectorList

pub struct SelectorList<Impl: SelectorImpl>(ThinArcUnion<SpecificityAndFlags, Component<Impl>, (), Selector<Impl>>);

A selector list is a tagged pointer with either a single selector, or a ThinArc<()> of multiple selectors.

Tuple Fields

0: ThinArcUnion<SpecificityAndFlags, Component<Impl>, (), Selector<Impl>>

Implementations

impl<Impl: SelectorImpl> SelectorList<Impl>

pub fn mark_as_intentionally_leaked(&self)

See Arc::mark_as_intentionally_leaked

pub fn from_one(selector: Selector<Impl>) -> Self

pub fn from_iter(iter: impl ExactSizeIterator<Item = Selector<Impl>>) -> Self

pub fn slice(&self) -> &[Selector<Impl>]

pub fn len(&self) -> usize

pub fn thin_arc_heap_ptr(&self) -> *const c_void

Returns the address on the heap of the ThinArc for memory reporting.

impl<Impl: SelectorImpl> SelectorList<Impl>

pub fn scope() -> Self

Returns a selector list with a single :scope selector (with specificity)

pub fn implicit_scope() -> Self

Returns a selector list with a single implicit :scope selector (no specificity)

pub fn parse<'i, 't, P>( parser: &P, input: &mut CssParser<'i, 't>, parse_relative: ParseRelative, ) -> Result<Self, ParseError<'i, P::Error>>

where P: Parser<'i, Impl = Impl>,

Parse a comma-separated list of Selectors. https://drafts.csswg.org/selectors/#grouping

Return the Selectors or Err if there is an invalid selector.

pub fn parse_disallow_pseudo<'i, 't, P>( parser: &P, input: &mut CssParser<'i, 't>, parse_relative: ParseRelative, ) -> Result<Self, ParseError<'i, P::Error>>

where P: Parser<'i, Impl = Impl>,

Same as parse, but disallow parsing of pseudo-elements.

pub fn parse_forgiving<'i, 't, P>( parser: &P, input: &mut CssParser<'i, 't>, parse_relative: ParseRelative, ) -> Result<Self, ParseError<'i, P::Error>>

where P: Parser<'i, Impl = Impl>,

fn parse_with_state<'i, 't, P>( parser: &P, input: &mut CssParser<'i, 't>, state: SelectorParsingState, recovery: ForgivingParsing, parse_relative: ParseRelative, ) -> Result<Self, ParseError<'i, P::Error>>

where P: Parser<'i, Impl = Impl>,

pub fn replace_parent_selector(&self, parent: &SelectorList<Impl>) -> Self

Replaces the parent selector in all the items of the selector list.

pub(crate) fn from_vec(v: Vec<Selector<Impl>>) -> Self

Creates a SelectorList from a Vec of selectors. Used in tests.

Trait Implementations

impl<Impl: Clone + SelectorImpl> Clone for SelectorList<Impl>

fn clone(&self) -> SelectorList<Impl>

Returns a copy of the value.

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

Performs copy-assignment from source.

impl<Impl: Debug + SelectorImpl> Debug for SelectorList<Impl>

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

Formats the value using the given formatter.

impl<Impl: PartialEq + SelectorImpl> PartialEq for SelectorList<Impl>

fn eq(&self, other: &SelectorList<Impl>) -> 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<Impl: SelectorImpl> ToCss for SelectorList<Impl>

fn to_css<W>(&self, dest: &mut 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<Impl: SelectorImpl> ToShmem for SelectorList<Impl>

where ThinArcUnion<SpecificityAndFlags, Component<Impl>, (), Selector<Impl>>: ToShmem,

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

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