Struct NodeSpec 

pub struct NodeSpec {
    pub node_key: NodeKey,
    pub type_id: GtsTypeId,
    pub name: Option<String>,
    pub payload: Option<Value>,
    pub expected_version: Option<i64>,
}

A node submitted for ingest. An upsert replaces the row’s mutable state wholesale: a field the request omits is cleared, never preserved.

Fields

node_key: NodeKey

type_id: GtsTypeId

name: Option<String>

payload: Option<Value>

GTS-validated attributes. None = no opinion on an existing row’s payload is not offered — ingest is replace, so None clears.

expected_version: Option<i64>

Optional compare-and-set on the node’s stored version.

A stored version is 1 or more and advances on every update. Some(n) with n >= 1 requires the stored version to be exactly n, and is a conflict when it is not – including when no node is stored under the key at all. Some(0) means “there must be no node under this key”: the one conditional a producer can make without a version to read back, and the way to claim a key exactly once across writers. Edges carry no version: their identity is derived from their endpoints.
