Structs§

AttrDef: One attribute of a class, as the schema declares it.
ClassDef: A class of the schema: what it is called and what it declares.
Element: One decoded CIM object: its class, its mRID, and its fields as written.
EnumDef: An enumeration of the schema and the values it allows.
EnumValueDef: One value of an enumeration.
FastHasher: A fast, non-cryptographic hasher for the decoder’s maps.
Schema: What one family’s schema says, as a table: its classes, the profiles it defines and the namespaces its vocabularies bind. Generated by cimgen, or read from RDFS at runtime (schema_source).
TypeRegistry: Namespace-aware class lookup, and every attribute each class declares.

LANG_KEY: The JSON key of an element’s language tags (Element::to_json_value).

foreign_class: The class of an object no class table knows — a SKOS concept, a PROV agent, a DCAT catalogue — named by its namespace and local name. One leaked ClassDef per distinct class, kept for the process like intern’s keys. Its qualified name is the class IRI, which no family’s by_type keys use.
intern: The one &'static copy of a field key the class tables do not hold — an attribute the element’s class does not declare, as written in the file or set from JSON. Each distinct key is leaked once and kept for the process; there are as many as distinct undeclared attribute names, not fields.

FastBuildHasher
FastMap
FastSet
FieldMap: An element’s fields, keyed by Class.attr. Keys are &'static: a declared attribute’s key is its id in the class table, any other goes through intern, so a key is allocated once per process rather than per field.
