Struct ChainScope 

pub struct ChainScope {
    pub root: EntityId,
    pub via: Vec<String>,
    pub direction: TraversalDirection,
    pub depth: usize,
}

What a caller asks for: a root entity, the rel-types to follow, the direction to follow them in, and how many hops.

Fields

root: EntityId

The entity the walk starts from; it is always part of the set.

via: Vec<String>

Rel-types followed at every hop. Validated against the mem’s schema vocabulary before the walk.

direction: TraversalDirection

Direction applied at every hop.

depth: usize

Maximum hops; usize::MAX for an unbounded walk.
