Enum selectors::parser::Combinator

pub enum Combinator {
    Child,
    Descendant,
    NextSibling,
    LaterSibling,
    PseudoElement,
    SlotAssignment,
    Part,
}

Variants

Child

Descendant

NextSibling

LaterSibling

PseudoElement

A dummy combinator we use to the left of pseudo-elements.

It serializes as the empty string, and acts effectively as a child combinator in most cases. If we ever actually start using a child combinator for this, we will need to fix up the way hashes are computed for revalidation selectors.

SlotAssignment

Another combinator used for ::slotted(), which represent the jump from a node to its assigned slot.

Part

Another combinator used for ::part(), which represents the jump from the part to the containing shadow host.

Implementations

impl Combinator

pub fn is_ancestor(&self) -> bool

Returns true if this combinator is a child or descendant combinator.

pub fn is_pseudo_element(&self) -> bool

Returns true if this combinator is a pseudo-element combinator.

pub fn is_sibling(&self) -> bool

Returns true if this combinator is a next- or later-sibling combinator.

impl Combinator

fn to_css_internal<W>(&self, dest: &mut W, prefix_space: bool) -> Resultwhere W: Write,

fn to_css_relative<W>(&self, dest: &mut W) -> Resultwhere W: Write,

Trait Implementations

impl Clone for Combinator

fn clone(&self) -> Combinator

Returns a copy of the value.

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

Performs copy-assignment from source.

impl Debug for Combinator

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

Formats the value using the given formatter.

impl PartialEq<Combinator> for Combinator

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

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

fn ne(&self, other: &Rhs) -> bool

This method tests for !=. The default implementation is almost always sufficient, and should not be overridden without very good reason.

impl ToCss for Combinator

fn to_css<W>(&self, dest: &mut W) -> Resultwhere 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 Combinator

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

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

impl Copy for Combinator

impl Eq for Combinator

impl StructuralEq for Combinator

impl StructuralPartialEq for Combinator
