Enum RowKind 

pub enum RowKind {
    Leaf,
    Coverage,
    Graph,
}

EXP-S (0.8.14 Slice 5, D1) — structural-role tag for a canonical row.

A SEPARATE axis from the doc-type kind (email/article/paper/meeting/ note/todo/doc/edge_fact): row_kind describes what structural role a row plays in the “one store, many indexes” substrate, not what document type it carries. Stored in canonical_nodes.row_kind (schema migration step 16).

Leaf is the default (a normal record; every existing/normal write is a leaf — back-compat preserving). Coverage = coverage/summary rows; Graph = graph structural rows. Engine-internal in 0.8.14 — there is NO public Py/TS SDK surface for row_kind this release (Leaf for all normal writes; Coverage/Graph are set only by internal paths). Cross-binding parity (X1) is a Slice-40 concern.

Implementations

impl RowKind

pub fn as_str(self) -> &'static str

On-disk canonical_nodes.row_kind spelling. Must match the migration step-16 DEFAULT 'leaf' and the schema vocabulary (D1).
