A compile-time description of how an Ash resource maps to the Neo4j graph.

ResourceMapping is the single source of truth for the graph shape of a resource. It is built from persisted DSL state via AshNeo4j.Resource.Info.mapping/1 and collects every piece of information the data layer needs without requiring scattered calls to individual Resource.Info accessors.

Fields

• :module — the Ash resource module (e.g. DiffoExample.Access.Shelf).
• :domain_label — PascalCase short name of the domain module, written on CREATE (e.g. :Access).
• :module_label — PascalCase short name of the resource module itself, always the resource's own name regardless of any fragment override (e.g. :Shelf).
• :label — the label used in MATCH for reads, updates, and deletes; comes from the DSL label option and may be a fragment base-type label (e.g. :Instance when Shelf extends BaseInstance).
• :domain_fragment_label — optional label contributed by a domain fragment using AshNeo4j.DataLayer.Domain (e.g. :Telco). nil when the domain declares none.
• :all_labels — full ordered list of labels written on CREATE: [domain_label, module_label, ...] including any base-type label from a resource fragment and the domain fragment label if present (e.g. [:Access, :Shelf, :Instance, :Telco]).
• :label_pair — the two-label pair [domain_label, module_label] used in MATCH for all read, update, delete, and aggregate operations. Always uniquely identifies this resource.
• :properties — keyword list of {ash_attribute_name, neo4j_property_name} translations; insertion order is preserved.
• :edges — list of AshNeo4j.EdgeDescriptor.t() structs, one per relate entry.
• :relationship_attributes — keyword list of {source_attribute, relationship_name} pairs for attributes that hold foreign keys; used to create edges during CREATE.
• :guards — list of {edge_label, direction, destination_label} tuples that block deletion.
• :skip — list of relationship names excluded from automatic edge management.
