Selector

rama::http::protocols::html::selector

Struct Selector 

pub struct Selector { /* private fields */ }
Available on crate features html and http and std only.
Expand description

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>) -> Selector

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

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

A class selector, e.g. .menu.

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

An id selector, e.g. #main.

pub fn any() -> Selector

The universal selector *.

pub fn of(compound: Compound) -> Selector

A selector from a single Compound.

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

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

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

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

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

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

§

impl Selector

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