Crate ant_types 

Record types of the open Antares (.ant) interchange format.

Everything that can appear in a .ant file lives here, one module per record plane:

• graph — Vertex and Edge, with typed properties and optional bitemporal validity.
• observation — append-only, source-bound atomic facts.
• evidence — the source material observations and edges cite.
• belief — versioned inferred state derived from observations.
• schema — OpenSPG-compatible type declarations.
• author — the provenance stamp records can carry.

Property values are typed at SQL fidelity (PropertyValue). Legacy scalars stay bare JSON on the wire; the typed additions (decimal, date, time, timestamp, uuid, bytes, sized ints, arrays) travel in a tagged {"$ant": ..., "v": ...} envelope, so a plain JSON document with a $ant field still round-trips as a document. Decimal is exact — an i128 of unscaled digits plus a scale, never f64 — so DECIMAL/NUMERIC columns survive digit for digit.

The container that carries these records (compression, manifest, trailer, hashing) is the antares-format crate; this crate is just the record vocabulary.

Modules

author

Record authorship — the provenance stamp carried on insight-plane records.

belief

Antares-native beliefs.

decimal

Exact decimal (SQL DECIMAL/NUMERIC, money).

error

Domain-layer error type shared by every record plane.

evidence

Antares-native first-class evidence.

graph

Graph data model: Vertex, Edge, PropertyValue, SubGraph.

ids

Identifier newtypes: tenant, project, vertex, edge, namespace, type name. Each is a thin wrapper so ids of different planes can’t be mixed up silently.

observation

Antares-native observations.

property

PropertyValue — the typed value of a vertex/edge property.

schema

Schema records: the OpenSPG-compatible type declarations that a .ant file can carry as schema_type records.
