Modules

cancel

Cooperative query cancellation.

profile

Profile-mode instrumentation for the pull executor.

Structs

BufferedRowSource

Buffered cursor backed by a pre-computed Vec<Row>. Used both as a simple “rows already collected” adapter and as the leaf fallback for operators whose internals still require full materialization.

CombinedResult

CombinedRow

ExecutionContext

Executor

GraphResult

HydratedGraph

HydratedNode

HydratedRelationship

LoraPath

A materialised path: alternating node/relationship IDs. nodes.len() == rels.len() + 1

MutableExecutionContext

MutableExecutor

MutablePullExecutor

Pull-based read-write executor. Wraps the existing MutableExecutor under the same row-cursor API. Mutations are applied during open_compiled; the returned cursor yields the resulting rows lazily.

PullExecutor

Pull-based read-only executor.

Row

Row layout: a positional vector indexed by VarId.0. Two reasons this beats the previous BTreeMap<VarId, RowEntry>:

RowArraysResult

RowsResult

Enums

ExecutorError

LoraValue

PropertyConversionError

Errors that can arise when converting a LoraValue into a PropertyValue for storage on a node or relationship.

QueryResult

ResultFormat

StreamShape

Classification of a compiled query, used by the database layer to decide whether db.stream needs a hidden staged transaction.

Traits

RowSource

Fallible pull-based row cursor.

Functions

classify_stream

Classify a compiled query for streaming. Treats any UNION branch the same as the head: a single mutating op anywhere across the compiled query promotes the whole query to Mutating.

collect_compiled

Drain a freshly opened cursor into a Vec<Row>. Convenience for callers that want the streaming entry point but a buffered result.

collect_compiled_with_deadline

collect_compiled bounded by a cooperative deadline.

compiled_result_columns

Result column names for a compiled query (head plan; UNION branches must produce the same shape so the head’s columns are authoritative).

drain

Drain a row source into a Vec<Row>, propagating the first error.

hydrate_row

Replace node / relationship id references in row with their full hydrated form (labels, type, properties), as every query result does.

lora_value_to_property

Fallible conversion used on every write path (set_property_from_expr, overwrite_entity_target, mutate_entity_target, eval_properties_expr, plus CREATE / MERGE). Rejects nodes, relationships and paths at any depth, and VECTOR values nested inside lists — everything else falls through to the infallible From implementation above. A top-level VECTOR property is always fine; only LISTs that directly contain a VECTOR entry are rejected. Index seeks also convert through here: a value that can’t be a property falls back to a scan, where it matches nothing.

plan_result_columns

Result column names derived from the compiled plan.
