Struct VariableReferenceValue 

#[repr(C)]
pub struct VariableReferenceValue {
    pub variable: CssString,
    pub fallback: UnparsedValue,
    pub has_fallback: bool,
}

A variable reference inside an unparsed Typed OM value.

This corresponds to CSSVariableReferenceValue in the Typed OM specification.

Fields

variable: CssString

The referenced custom property name.

This corresponds to the variable attribute of CSSVariableReferenceValue.

fallback: UnparsedValue

The fallback value, if present.

This corresponds to the fallback attribute of CSSVariableReferenceValue. When has_fallback is false, this value must be ignored. When has_fallback is true, this contains the fallback tokens (which may be empty).

has_fallback: bool

Whether a fallback was explicitly provided.

This is needed to distinguish between the absence of a fallback (var(--a)) and an explicitly empty fallback (var(--a,)), which are observable via Typed OM.
