Struct Selector 

pub struct Selector { /* private fields */ }

Available on crate feature html only.

A parsed CSS selector string.

A selector string may contain a comma-separated list of complex selectors (e.g. "a, .b > c"); the Selector matches an element if any of those complex selectors matches it.

Implementations

impl Selector

pub fn tag(name: impl AsRef<str>) -> Self

A type (tag) selector, e.g. div. Shorthand for Selector::of(Compound::tag(name)).

pub fn class(name: impl AsRef<str>) -> Self

A class selector, e.g. .menu.

pub fn id(name: impl AsRef<str>) -> Self

An id selector, e.g. #main.

pub fn any() -> Self

The universal selector *.

pub fn of(compound: Compound) -> Self

A selector from a single Compound.

pub fn child(self, compound: Compound) -> Self

Extends the current complex selector with a child combinator: self > compound.

pub fn descendant(self, compound: Compound) -> Self

Extends the current complex selector with a descendant combinator: self compound.

pub fn or(self, other: Self) -> Self

Adds other’s complex selectors as further alternatives (the comma list): self, other.

impl Selector

pub fn matches<S: SelectorSubject>(&self, subject: &S) -> bool

Returns whether subject matches this selector.

Trait Implementations

impl Clone for Selector

fn clone(&self) -> Selector

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for Selector

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

Formats the value using the given formatter.

impl Display for Selector

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

Formats the value using the given formatter.

impl Eq for Selector

impl FromStr for Selector

type Err = SelectorError

The associated error which can be returned from parsing.

fn from_str(s: &str) -> Result<Self, Self::Err>

Parses a string s to return a value of this type.

impl PartialEq for Selector

fn eq(&self, other: &Selector) -> 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.
