    And(Vec<ChunkPredicate>),
}

Narrow predicate representation for the vectorized pipeline (Phase 2).

Covers only simple conjunctive property predicates that can be compiled directly from a Cypher WHERE clause without a full expression evaluator. Unsupported WHERE shapes (CONTAINS, function calls, subqueries, cross- variable predicates) fall back to the row-at-a-time engine.

All comparisons are on the raw u64 storage encoding. NULL handling: IsNull matches rows where the column’s null bitmap bit is set; all comparison variants (Eq, Lt, etc.) automatically fail for null rows.

Variants

Eq

Equal: col_id = rhs_raw.

Fields

col_id: u32

rhs_raw: u64

Ne

Not equal: col_id <> rhs_raw.

Fields

col_id: u32

rhs_raw: u64

Gt

Greater-than: col_id > rhs_raw (unsigned comparison on raw bits).

Fields

col_id: u32

rhs_raw: u64

Ge

Greater-than-or-equal: col_id >= rhs_raw.

Fields

col_id: u32

rhs_raw: u64

Lt

Less-than: col_id < rhs_raw.

Fields

col_id: u32

rhs_raw: u64

Le

Less-than-or-equal: col_id <= rhs_raw.

Fields

col_id: u32

rhs_raw: u64

IsNull

Is-null: matches rows where the column’s null-bitmap bit is set.

Fields

col_id: u32

IsNotNull

Is-not-null: matches rows where the column’s null-bitmap bit is clear.

Fields

col_id: u32

And(Vec<ChunkPredicate>)

Conjunction of child predicates (all must pass).

Implementations

impl ChunkPredicate

pub fn eval(&self, chunk: &DataChunk, row_idx: usize) -> bool

Evaluate this predicate for a single physical row index.

Returns true if the row should remain live.

Trait Implementations

impl Clone for ChunkPredicate

fn clone(&self) -> ChunkPredicate

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for ChunkPredicate

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

Formats the value using the given formatter.
