Enum OptionValue 

#[non_exhaustive]
pub enum OptionValue<'a> {
    Literal(Literal<'a>),
    Variable(VariableRef<'a>),
}

An option’s value: a literal or a variable.

Variants (Non-exhaustive)

Non-exhaustive enums could have additional variants added in future. Therefore, when matching against variants of non-exhaustive enums, an extra wildcard arm must be added to account for any future variants.

Literal(Literal<'a>)

opt=|literal| or opt=literal.

Variable(VariableRef<'a>)

opt=$var.
