Struct LinkedDataStore

Source 
pub struct LinkedDataStore<'a> {
    pub linkage: &'a RootedLinkage,
    pub store: &'a dyn PackageStore,
}
Expand description

A LinkedDataStore is a wrapper around a PackageStore (i.e., a package store where we can also resolve types to defining IDs) along with a specific linkage. These two together allow us to resolve modules and types in a way that is consistent with the linkage provided and allow us to then pass this into the VM. Until we have a linkage set it is not possible to construct a valid DataStore for execution in the VM as it needs to be able to resolve modules under a specific linkage.
