Variants

Nothing

No token serialization type.

WhiteSpace

The <whitespace-token> type.

AtKeywordOrHash

Number

The <number-token> type.

Dimension

The <dimension-token> type.

Percentage

The <percentage-token> type.

UrlOrBadUrl

The <url-token> or <bad-url-token> type.

Function

The <function-token> type.

Ident

The <ident-token> type.

CDC

The --> <CDC-token> type.

DashMatch

The |= <dash-match-token> type.

SubstringMatch

The *= <substring-match-token> type.

OpenParen

The <(-token> type.

DelimHash

The # <delim-token> type.

DelimAt

The @ <delim-token> type.

DelimDotOrPlus

The . or + <delim-token> type.

DelimMinus

The - <delim-token> type.

DelimQuestion

The ? <delim-token> type.

DelimAssorted

The $, ^, or ~ <delim-token> type.

DelimEquals

The = <delim-token> type.

DelimBar

The | <delim-token> type.

DelimSlash

The / <delim-token> type.

DelimAsterisk

The * <delim-token> type.

DelimPercent

The % <delim-token> type.

Other

A type indicating any other token.

Implementations

impl TokenSerializationType

pub fn nothing() -> TokenSerializationType

👎Deprecated since 0.32.1: use TokenSerializationType::Nothing or TokenSerializationType::default() instead

Return a value that represents the absence of a token, e.g. before the start of the input.

pub fn set_if_nothing(&mut self, new_value: TokenSerializationType)

If this value is TokenSerializationType::Nothing, set it to the given value instead.

pub fn needs_separator_when_before(self, other: TokenSerializationType) -> bool

Return true if, when a token of category self is serialized just before a token of category other with no whitespace in between, an empty comment /**/ needs to be inserted between them so that they are not re-parsed as a single token.

See https://drafts.csswg.org/css-syntax/#serialization

Trait Implementations

impl Clone for TokenSerializationType

fn clone(&self) -> TokenSerializationType

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for TokenSerializationType

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

Formats the value using the given formatter.

impl Default for TokenSerializationType

fn default() -> TokenSerializationType

Returns the “default value” for a type.

impl PartialEq for TokenSerializationType

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