Module query 

Query primitives.

Two builder structs (NodeQuery, EdgeQuery) plus a small traverse function for breadth-first walks. The query language is intentionally tiny; the goal is to expose composable predicates rather than to reinvent Cypher / Gremlin.

Structs

EdgeQuery

Filter for Edges incident to a given node.

NodeQuery

Filter for Nodes.

Enums

EdgeDirection

Edge direction relative to an anchor node.

Functions

traverse

Breadth-first traversal that walks edges matching edge_label outward from start, returning every node reached within max_depth.
