Enum lightningcss::selector::Combinator

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

A combinator.

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.

DeepDescendant

Non-standard Vue >>> combinator. https://vue-loader.vuejs.org/guide/scoped-css.html#deep-selectors

Deep

Non-standard /deep/ combinator. Appeared in early versions of the css-scoping-1 specification: https://www.w3.org/TR/2014/WD-css-scoping-1-20140403/#deep-combinator And still supported as an alias for >>> by Vue.

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.

pub fn is_tree_combinator(&self) -> bool

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<(), Error>

Formats the value using the given formatter.

impl<'de> Deserialize<'de> for Combinator

fn deserialize<__D>( __deserializer: __D ) -> Result<Combinator, <__D as Deserializer<'de>>::Error>

where __D: Deserializer<'de>,

Deserialize this value from the given Serde deserializer.

impl Hash for Combinator

fn hash<__H>(&self, state: &mut __H)

where __H: Hasher,

Feeds this value into the given Hasher.

fn hash_slice<H>(data: &[Self], state: &mut H)

where H: Hasher, Self: Sized,

Feeds a slice of this type into the given Hasher.

impl<'any> IntoOwned<'any> for Combinator

type Owned = Combinator

A variant of Self with a new lifetime.

fn into_owned(self) -> Combinator

Make lifetime of self 'static.

impl JsonSchema for Combinator

fn schema_name() -> String

The name of the generated JSON Schema.

fn schema_id() -> Cow<'static, str>

Returns a string that uniquely identifies the schema produced by this type.

fn json_schema(gen: &mut SchemaGenerator) -> Schema

Generates a JSON Schema for this type.

fn is_referenceable() -> bool

Whether JSON Schemas generated for this type should be re-used where possible using the $ref keyword.

impl PartialEq 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 Serialize for Combinator

fn serialize<__S>( &self, __serializer: __S ) -> Result<<__S as Serializer>::Ok, <__S as Serializer>::Error>

where __S: Serializer,

Serialize this value into the given Serde serializer.

impl ToCss for Combinator

fn to_css<W>(&self, dest: &mut W) -> Result<(), Error>

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 ToCss for Combinator

fn to_css<W>( &self, dest: &mut Printer<'_, '_, '_, W> ) -> Result<(), PrinterError>

where W: Write,

Serialize self in CSS syntax, writing to dest.

fn to_css_string( &self, options: PrinterOptions<'_> ) -> Result<String, PrinterError>

Serialize self in CSS syntax and return a string.
