PseudoClass

Pseudo-class

Value contains ident without :. Selector: "nth-child", value: The thing between the braces - Some("3")

https://www.w3.org/TR/CSS21/selector.html#pseudo-class-selectors

Fields

selector: &'a str

value: Option<&'a str>

Combinator(Combinator)

Combinator

Comma

Rules separator

BlockStart

Block start

Indicates {.

Trait Implementations

impl<'a> Debug for Token<'a>

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

Formats the value using the given formatter.

impl<'a> PartialEq for Token<'a>

fn eq(&self, other: &Token<'a>) -> 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.
