Struct ItemReferences 

Source 
pub struct ItemReferences {
    pub ids: BTreeSet<String>,
    pub named_relations: BTreeSet<UnresolvedItemName>,
    pub named_funcs: BTreeSet<UnresolvedItemName>,
    pub named_types: BTreeSet<UnresolvedItemName>,
    pub named_array_elements: BTreeSet<UnresolvedItemName>,
}
Expand description

The catalog item references appearing in a statement.

User statements are normalized and have IDs in its relation and type references (e.g. [u1 AS db.schema.name]). For references that don’t have IDs, we create separate named_* buckets that contain their qualified names.

Fields§

§ids: BTreeSet<String>

Catalog IDs from RawItemName::Id references

§named_relations: BTreeSet<UnresolvedItemName>

Named relations that don’t carry an ID. Most commonly seen in builtin statements since they are not normalized. CTE names are excluded: a name bound by a WITH clause refers to the query-local binding rather than a catalog item, so recording it would fabricate an edge to any catalog object that happens to share the name.

§named_funcs: BTreeSet<UnresolvedItemName>§named_types: BTreeSet<UnresolvedItemName>§named_array_elements: BTreeSet<UnresolvedItemName>

Data-type references written T[]. These are reported separately from named_types since T[] maps to the named type _T.
