Struct Expand 

pub struct Expand<'a, O: Operator + 'a> { /* private fields */ }

Expands a NodeRef column by looking up neighbors in a CSR.

For each node in src_col, produces neighbor node IDs in dst_col. Preserves group multiplicity.

Implementations

impl<'a, O: Operator> Expand<'a, O>

pub fn new( inner: &'a mut O, src_col: &str, dst_col: &str, csr: &'a CsrForward, ) -> Self

Trait Implementations

impl<'a, O: Operator> Operator for Expand<'a, O>

fn next_chunk(&mut self) -> Result<Option<FactorizedChunk>>

fn collect_all(&mut self) -> Result<Vec<FactorizedChunk>>

Drain all chunks and materialize as a Vec.
