Implementations

impl SubstitutionFunction

pub fn parse( kind: SubstitutionFunctionKind, input: &mut Parser<'_>, context: &mut SubstitutionParserContext<'_>, ) -> Result<Self, ParseError>

Parses the arguments of a substitution function of the given kind, with input positioned inside its nested block.

pub fn reference_flags(&self) -> ReferenceFlags

The reference flags to record for a reference to this function.

fn replace<'a>( &'a self, source: &'a VariableValue, context: &mut SubstitutionReplacementContext<'a, '_, '_, '_>, ) -> Result<Substitution<'a>, ()>

pub fn for_each_unparsed_value<F>(&self, f: F)

where F: FnMut(&ArbitraryDeclarationValue),

Calls f for each arbitrary declaration value nested in the function.
