pub type ShorthandsWithPropertyReferencesCache = FxHashMap<(ShorthandId, LonghandId), PropertyDeclaration>;
Expand description

A simple cache for properties that come from a shorthand and have variable references.

This cache works because of the fact that you can’t have competing values for a given longhand coming from the same shorthand (but note that this is why the shorthand needs to be part of the cache key).
