Struct TraversalStep 

pub struct TraversalStep {
    pub target_labels: Vec<String>,
    pub rel_type: Option<String>,
    pub direction: Direction,
    pub filter: Option<Expr>,
}

One level of an alias traversal path (see RelatedSpec::steps).

Fields

target_labels: Vec<String>

Labels the endpoint at this level must carry (empty = any label).

rel_type: Option<String>

Relationship type filter at this level; None matches any type.

direction: Direction

Edge direction at this level.

filter: Option<Expr>

Endpoint predicates evaluated on the record at this level (nested label blocks are separate steps, not part of this filter).
