Enum RegistrationEntry

    Scalar {
        qname: String,
        signature: WireFnSignature,
    },
    Aggregate {
        qname: String,

    Algorithm {

    },
}

One registration entry — a single qname plus its kind + signature.

Variants

Scalar

A Cypher scalar function.

Fields

qname: String

Fully-qualified name ("ns.fn").

signature: WireFnSignature

Signature.

Aggregate

A Cypher aggregate function. Wire shape mirrors Scalar with the state type carried as a separate WireArgType.

Fields

qname: String

Fully-qualified name.

signature: WireFnSignature

Per-row input + return types.

state: WireArgType

State type — opaque to the wire; Adapter side wraps as Arrow Binary.

Procedure

A Cypher procedure.

Fields

qname: String

Fully-qualified name.

args: Vec<WireArgType>

Argument signatures.

yields: Vec<WireArgType>

Yielded column types, in declared order.

mode: String

Mode — "read", "write", "schema", or "dbms". Default "read".

Algorithm

A GraphCompute algorithm. Its guest export drives the coarse kernels via the uni_graph_call host fn and emits its per-vertex result (proposal §4.6). yields become the AlgorithmSignature::output_fields.

Fields

qname: String

Fully-qualified name.

args: Vec<WireArgType>

Argument signatures (excluding the injected session id).

yields: Vec<String>

Yielded columns as "name:type" strings (e.g. "score:float"), so the emitted column and the special nodeId column bind by name.
