A raw CSS token.

Variants

Ident(CowArcStr<'a>)

A <ident-token>

AtKeyword(CowArcStr<'a>)

A <at-keyword-token>

The value does not include the @ marker.

Hash(CowArcStr<'a>)

A <hash-token> with the type flag set to “unrestricted”

The value does not include the # marker.

IDHash(CowArcStr<'a>)

A <hash-token> with the type flag set to “id”

The value does not include the # marker.

String(CowArcStr<'a>)

A <string-token>

The value does not include the quotes.

UnquotedUrl(CowArcStr<'a>)

A <url-token>

The value does not include the url( ) markers. Note that url( <string-token> ) is represented by a Function token.

Delim(char)

A <delim-token>

Number

A <number-token>

Fields

has_sign: bool

Whether the number had a + or - sign.

This is used is some cases like the <An+B> micro syntax. (See the parse_nth function.)

value: f32

The value as a float

int_value: Option<i32>

If the origin source did not include a fractional part, the value as an integer.

Percentage

A <percentage-token>

Fields

has_sign: bool

Whether the number had a + or - sign.

unit_value: f32

The value as a float, divided by 100 so that the nominal range is 0.0 to 1.0.

int_value: Option<i32>

If the origin source did not include a fractional part, the value as an integer. It is not divided by 100.

Dimension

A <dimension-token>

Fields

has_sign: bool

Whether the number had a + or - sign.

This is used is some cases like the <An+B> micro syntax. (See the parse_nth function.)

value: f32

The value as a float

int_value: Option<i32>

If the origin source did not include a fractional part, the value as an integer.

unit: CowArcStr<'a>

The unit, e.g. “px” in 12px

WhiteSpace(CowArcStr<'a>)

A <whitespace-token>

Comment(CowArcStr<'a>)

A comment.

The CSS Syntax spec does not generate tokens for comments, But we do, because we can (borrowed &str makes it cheap).

The value does not include the /* */ markers.

Colon

A : <colon-token>

Semicolon

A ; <semicolon-token>

Comma

A , <comma-token>

IncludeMatch

A ~= <include-match-token>

DashMatch

A |= <dash-match-token>

PrefixMatch

A ^= <prefix-match-token>

SuffixMatch

A $= <suffix-match-token>

SubstringMatch

A *= <substring-match-token>

CDO

A <!-- <CDO-token>

CDC

A --> <CDC-token>

Function(CowArcStr<'a>)

A <function-token>

The value (name) does not include the ( marker.

ParenthesisBlock

A <(-token>

SquareBracketBlock

A <[-token>

CurlyBracketBlock

A <{-token>

BadUrl(CowArcStr<'a>)

A <bad-url-token>

This token always indicates a parse error.

BadString(CowArcStr<'a>)

A <bad-string-token>

This token always indicates a parse error.

CloseParenthesis

A <)-token>

When obtained from one of the Parser::next* methods, this token is always unmatched and indicates a parse error.

CloseSquareBracket

A <]-token>

When obtained from one of the Parser::next* methods, this token is always unmatched and indicates a parse error.

CloseCurlyBracket

A <}-token>

When obtained from one of the Parser::next* methods, this token is always unmatched and indicates a parse error.
