Enum ChunkedPlan 

pub enum ChunkedPlan {
    Scan,
    OneHop,
    TwoHop,
    MutualNeighbors,
}

Shape selector for the chunked vectorized pipeline (Phase 4, spec §2.3).

Replaces the cascade of can_use_* boolean guards with a typed plan enum. Engine::try_plan_chunked_match returns one of these variants (or None to indicate the row engine should be used), and dispatch is a match with no further if can_use_* calls.

Each variant may carry shape-specific parameters in future phases. For now all resolution happens in the execute_*_chunked methods.

Variants

Scan

Single-label scan only — no relationship hops.

OneHop

Single-hop directed traversal.

TwoHop

Two-hop same-rel-type directed traversal.

MutualNeighbors

Mutual-neighbors: (a)-[:R]->(x)<-[:R]-(b) with both a and b bound.

Trait Implementations

impl Clone for ChunkedPlan

fn clone(&self) -> ChunkedPlan

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for ChunkedPlan

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

Formats the value using the given formatter.

impl Display for ChunkedPlan

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

Formats the value using the given formatter.

impl PartialEq for ChunkedPlan

fn eq(&self, other: &ChunkedPlan) -> 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.
