Implementations§

source§

impl TokenSerializationType

source

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.

source

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

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

source

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

See https://github.com/w3c/csswg-drafts/issues/4088 for the DelimPercent bits.

impl PartialEq for TokenSerializationType

source§

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