Struct InMemoryNeighbors

Source

pub struct InMemoryNeighbors<'a> { /* private fields */ }

Expand description

Neighbours resolved against an in-memory edge list.

graph export/graph traverse already load the whole namespace to render nodes and edges, so re-querying SQLite per hop would be pure waste.

Implementations§

Source §

impl<'a> InMemoryNeighbors<'a>

Source

pub fn new( edges: &'a [MemoryEdge], id_to_name: &'a HashMap<i64, String>, ) -> Self

Builds a source over a preloaded edge list and its id→name index.
