Batch(Vec<WalRecord>)

One WAL frame = one atomic batch. Nested Batch inside a Batch is invalid: encode_record debug-asserts against it, and decode_all treats a frame whose payload deserialises to a nested Batch as corrupt (stops cleanly before that frame, returning the valid prefix).

RebuildRule

Recompute one rule from scratch (un-trip / repair). Appended after Batch; bincode discriminant is 9. Batch stays at 8.

Fields

name: String

CreateView

Create (or restore) a materialized property view. Bincoded ViewDef bytes keep core-storage free of core-rules types. Discriminant 10.

Fields

def_bytes: Vec<u8>

DeleteView

Delete a named view and remove its values from all nodes. Discriminant 11.

Fields

name: String

EnableFulltext

Enable full-text indexing on all nodes of label for field field. The index is rebuilt from live data on open; this record only persists the declaration. Discriminant 12.

Fields

label: String

field: String

DisableFulltext

Disable full-text indexing for (label, field) and drop its postings. Discriminant 13.

Fields

label: String

field: String

InsertNodeId

Insert a node using interned label/field ids. Key remains a string once. Discriminant 14.

Fields

label: u32

key: String

props: Vec<(u32, Value)>

SetPropId

Set a property using dense node id and interned field id. Discriminant 15.

Fields

id: u32

field: u32

value: Value

InsertEdgeId

Insert an edge using interned etype and dense node ids. Discriminant 16.

Fields

etype: u32

src: u32

dst: u32

Intern

Bind intern id id to text so subsequent *Id records can replay without a snapshot intern table. Discriminant 17. Apply is idempotent when the string is already bound to id.

Discriminant order is append-order, not emit-order: in a WAL stream Intern always precedes the *Id records that reference it, even though it carries the highest discriminant of the 14–17 group.

Fields

id: u32

text: String

DerivedEdgeAdded

A rule-derived edge was added. Discriminant 18.

Fields

rule: String

edge_type: String

src_key: String

dst_key: String

DerivedEdgeRetracted

A rule-derived edge was retracted. Discriminant 19.

Fields

rule: String

edge_type: String

src_key: String

dst_key: String

RenameNode

Rename a node’s key. Dense id is unchanged. Discriminant 20.

Fields

old_key: String

new_key: String

EnableIndex

Enable an equality index on (label, field). Discriminant 21.

Fields

label: String

field: String

DisableIndex

Disable the equality index on (label, field) and drop its postings. Discriminant 22.

Fields

label: String

field: String
