A filter predicate applied to candidate nodes.

Variants

LogicalIdEq(String)

Match nodes with the exact logical ID.

KindEq(String)

Match nodes with the exact kind.

JsonPathEq

Equality check on a JSON property at the given path.

Fields

path: String

JSON path expression (e.g. $.status).

value: ScalarValue

Value to compare against.

JsonPathCompare

Ordered comparison on a JSON property at the given path.

Fields

path: String

JSON path expression.

op: ComparisonOp

Comparison operator.

value: ScalarValue

Value to compare against.

SourceRefEq(String)

Match nodes with the exact source_ref.

ContentRefNotNull

Match nodes where content_ref is not NULL (i.e. content proxy nodes).

ContentRefEq(String)

Match nodes with the exact content_ref URI.

JsonPathFusedEq

Fused equality check on a JSON text property at the given path.

Unlike Predicate::JsonPathEq, this variant is classified as fusable by crate::fusion::is_fusable and is pushed into the search CTE’s inner WHERE clause so the CTE LIMIT applies after the predicate runs. The caller opts into fusion by registering an FTS property schema that covers the path; the tethered builder enforces that gate at filter-add time.

Fields

path: String

JSON path expression (e.g. $.status).

value: String

Text value to compare against.

JsonPathFusedTimestampCmp

Fused ordered comparison on a JSON integer/timestamp property at the given path. See Predicate::JsonPathFusedEq for the fusion contract.

Fields

path: String

JSON path expression.

op: ComparisonOp

Comparison operator.

value: i64

Integer value to compare against (epoch seconds for timestamp semantics).

JsonPathFusedBoolEq

Fused equality check on a JSON boolean property at the given path. See Predicate::JsonPathFusedEq for the fusion contract. The boolean is stored as SQLite integer 1/0.

Fields

path: String

JSON path expression (e.g. $.resolved).

value: bool

Boolean value to compare against (stored as 1 or 0).

EdgePropertyEq

Equality check on a JSON property of the traversed edge at the given path.

Structurally identical to Predicate::JsonPathEq but targets e.properties on the edge row rather than n.properties on the target node. Only valid inside an expansion slot’s edge_filter.

Fields

path: String

JSON path expression (e.g. $.rel).

value: ScalarValue

Value to compare against.

EdgePropertyCompare

Ordered comparison on a JSON property of the traversed edge at the given path.

Structurally identical to Predicate::JsonPathCompare but targets e.properties on the edge row rather than n.properties on the target node. Only valid inside an expansion slot’s edge_filter.

Fields

path: String

JSON path expression.

op: ComparisonOp

Comparison operator.

value: ScalarValue

Value to compare against.

JsonPathFusedIn

Fused IN-set check on a JSON text property at the given path.

Like Predicate::JsonPathFusedEq, this variant is classified as fusable and is pushed into the search CTE’s inner WHERE clause. The caller must have a registered FTS property schema for the path.

Fields

path: String

JSON path expression (e.g. $.status).

values: Vec<String>

Non-empty set of text values; the node must match at least one.

JsonPathIn

IN-set check on a JSON property at the given path.

Unlike Predicate::JsonPathFusedIn, this variant is not fusable and is applied as a residual WHERE clause on the Nodes driver scan.

Fields

path: String

JSON path expression (e.g. $.category).

values: Vec<ScalarValue>

Non-empty set of values; the node must match at least one.

Trait Implementations

impl Clone for Predicate

fn clone(&self) -> Predicate

Returns a duplicate of the value.

fn clone_from(&mut self, source: &Self)

Performs copy-assignment from source.

impl Debug for Predicate

fn fmt(&self, f: &mut Formatter<'_>) -> Result

Formats the value using the given formatter.

impl PartialEq for Predicate

fn eq(&self, other: &Predicate) -> bool

Tests for self and other values to be equal, and is used by ==.

fn ne(&self, other: &Rhs) -> bool

Tests for !=. The default implementation is almost always sufficient, and should not be overridden without very good reason.
