Struct scraper::selector::Selector

pub struct Selector { /* private fields */ }

Wrapper around CSS selectors.

Represents a “selector group”, i.e. a comma-separated list of selectors.

Implementations

impl Selector

pub fn parse(selectors: &str) -> Result<Self, SelectorErrorKind<'_>>

Parses a CSS selector group.

pub fn matches(&self, element: &ElementRef<'_>) -> bool

Returns true if the element matches this selector.

pub fn matches_with_scope( &self, element: &ElementRef<'_>, scope: Option<ElementRef<'_>> ) -> bool

Returns true if the element matches this selector. The optional scope argument is used to specify which element has :scope pseudo-class. When it is None, :scope will match the root element.

Trait Implementations

impl Clone for Selector

fn clone(&self) -> Selector

Returns a copy 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 PartialEq for Selector

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

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<'i> TryFrom<&'i str> for Selector

type Error = SelectorErrorKind<'i>

The type returned in the event of a conversion error.

fn try_from(s: &'i str) -> Result<Self, Self::Error>

Performs the conversion.

impl Eq for Selector
